Dear AquaTune, I installed my AquaTunePLUS system on my 2002 Nissan Altima, 4 cyl. on 6/30/05 and left the next morning to visit our twin grandsons in Orange County, Calif. The increase in power was immediately evident – I couldn’t wait to check the mileage, so when I got to Barstow, Calif., a total of 159 miles, I filled up to check my mileage. I was previously getting 21 mpg. I got 30mpg driving at 76mph on the cruise control – a whopping 42% increase! I also noticed that my temperature gauge was registering a lower temp. on my return trip to Nevada. As I entered Baker, Calif., called the Gateway to Death Valley – I knew I had to negotiate the Baker Grade – a 17 mile upgrade that starts at about 250 feet above sea level and goes to over 4,000 feet at the top. At the 16 mile warning there is a yellow Caution sign that reads “Turn off A/C for the next 16 miles to avoid overheating”, so I did just the opposite – I set the A/C at max. and the cruise control at 80mph. I passed over 18 cars on the side of the road that had heat related failures. When I crested at the top my temperature had not moved a centimeter! The two words I use to describe the performance are “Awesome & Unbelievable”. Thanks to AquaTune for their excellent assistance with the mechanic installing the system! Sincerely, Don Bond, Las Vegas (PS - - This customer then became a Master Distributor in two regions.)

Dear AquaTune: I’m the worst skeptic in the world and a good tester because I leave no stone unturned! Now I know that you’re not just perpetrating a fraud. This system definitely works! I got an astounding 18.5 mpg on the run where I was typically getting 11 mpg previously. Let me tell you, my ’85 Bronco, 5.8L, 4 valve HO Ford engine with 127K miles on it is running better than ever before. It is smoother, quieter and my sticky valve is stuck no more. Even the rattle in my CAT converter is gone. Can’t explain this but, it sure is running smooth and cooler and no more predetonation. I am stoked. I can bury the needle without even flooring the engine. I have power to spare on the top end. It feels like I have a ram air system installed. You keep your foot steady and it just keeps accelerating. My Bronco feels like a mustang on the top end. Even at 85mph, when you step on it, it puts you back in your seat. The installation was fast and though I made a lot of mistakes, your Tech support was wonderful. I never felt left alone. Thank you AquaTune for a wonderful product! Stephen C., Washington

Dear AquaTune folks, I had Nick install an AquaTune unit in March of 2004. I am a sales rep. and travel 50-60,000 miles per year. I’ve driven my 1992 SAAB 9000 Turbo 30-40,000 miles with this unit on it. The power is unbelievable and this 2.3L turbo runs like a supercharged V-8. The fuel economy went from 25-26 mpg to 29-30 mpg on regular unleaded gasoline. By now I have a total of 250,000 miles on this engine and it runs as good now as when I first bought it. I highly recommend this fine system. Consequently I’ve chosen to become an Authorized Sales Rep. on behalf of AquaTune. Sincerely, Wayne Burns, Cheyenne, WY

Dear sir or madam, Prior to ordering your product, the AquaTunePLUS, I asked you if this system would increase my fuel economy because I was already getting pretty decent mileage at the time. Not only did I prove that it would, my mileage increased by 40% consistently. Your system is absolutely incredible! The horsepower is just as impressive. Also, my transmission doesn’t downshift anymore when I go up steep grades. I will be telling everyone I know about this product because I definitely got my moneys worth. Please tell your sales staff thank you for the excellent job. C.I. in Florida (This gentleman drives a ’94 Grand Prix SE with 3.1L engine.)

Hello AquaTune, I don't know why I waited over a year after receiving your e-mail indicating your Aqua-Tune would work on my 1974 BMW R90/6 Motorcycle! I installed the Aqua-Thrust kit late June '04 and what a pleasure to ride now! I maintain a log of all my fuel use - before Aqua-Thrust I averaged 44mpg including riding 2-up, pulling a trailer and having to gear-down on steeper grades. Now it's a WHOLE DIFFERENT experience! My wife and I recently went on a two week trip to Vermont, New Hampshire & Maine, riding 2-up with a UNI-GO trailer - over 2K (2,000) miles and the power & mileage are GREAT! – and no more downshifting - I was able to increase my speed going uphill without sneaking another gear! And, no more pre-detonation! Mileage is averaging 50 to 52mpg & the BEEMER (BMW) has never run 'sweeter' - I 'sync'd' the carbs with a Twin-Max before installing your product but, now it runs even smoother. I highly recommend Aqua-Thrust to any other 'airhead'riders out there - very easy to install - and start having some fun pulling those hills without shifting so much plus a much smoother running 'boxer'! Give it a try - I believe you'll be wondering why you didn't "hook-up' to Aqua -Thrust long before! AquaTune, if anyone wants to contact me regarding these results, Best regards, Bruce Hirschey, New York (An ‘airhead’ with an AquaThrust – 1974 R90/6 BMW motorcycle)

Hi, Just to let you know I feel I’m very fortunate, that is “blessed”, to have called you and bought your water injection system for my car! My ’97 Grand Marquis is now getting the gas mileage of a Taurus. Namely, 26-28 mpg and this at 75 mph on the expressway, and 21 mpg in the city. This, after having gotten 17, at best, on the expressway and 14 in town and the increase in hp is phenomenal! Needless to say, I’m very satisfied!!! As you know, I now have three (3) AquaTune injection systems. Need I say more? You can rest assured, I’m telling everyone I know about your product!!! My sincere thanks, Larry N., Michigan

Hello AquaTune, I just wanted to let you know how well the AquaTunePLUS worked on my ’04 Toyota. I have the Scion XB. I use this vehicle mostly in my business and I drive every bit of 22,000 miles in a year. Before I installed the AquaTunePLUS on my vehicle, my combined mileage, at best, was 28-29mpg. Now it is 37mpg, that’s just a little over a 32% increase! Now for the horsepower, it is awesome for a little 1.5L with an automatic trans. I also installed a second AquaTunePLUS that on my wife’s ’04 Nissan Quest the other day. This vehicle has the 3.5L engine. My wife loves it! I’ll let you know the results on this one shortly. Thanks for a such a great product! C. & B., California

Dear AquaTune, It’s me, Larry, again. After buying and installing this new product of yours, AquaTunePLUS on our ’89 Ford Escort with a 1.9L engine, I was absolutely floored at the increase in the fuel economy! Not to mention the increase in the horsepower. Previously, this vehicle had an AquaTune Classic unit on it. With this system it takes everything NOT to spin the tires. I think my wife thinks I’m doing this on purpose. The fuel economy went from 20 mpg to an astounding 37mpg! Please note, I just bought a 2004 Ford Focus (with 16 valve ram induction and all the goodies) that is designed to get the best of fuel economy and this AquaTunePlus is outperforming the Focus, not only in fuel economy but also horsepower. Thank you very much. I am so happy with these results I’m thinking of calling the news media, if that’s all right with you. Larry N. (This gentleman has an AquaTunePlus fitted with the 14k gold-filled hydrogen reactor.)

Dear AquaTune, Had your system put on my daughter’s 1990 Isuzu pickup. I know I called you to let you know how it went because I was impressed. Here are the figures showing the improvement. Namely, we are now getting an additional 7.2 miles per gallon which comes to about a 39% increase on this vehicle. We also noticed a smoothness in how the engine runs and the horsepower is tremendous. Thank you again, Robert R., Oregon City, OR

Attention Nick @ AquaTune: I don’t know if you’ll remember me, I ordered the AquaTune kit for my ’99 Pontiac Grand Prix with an ’04 supercharged 3.8L engine. Well, you were right on all points, it definitely exceeded all my expectations! It is every bit comparable to Nitrous without the harm to the engine. I had a friend driving with me to show him the difference and when we hit boost, it flat put us back in the seat, and all he could say was “WOW”! Now for the fuel increase: it went from 32 mpg on the highway to 42mpg. Not bad, huh? Anyway, I’d really be interested in selling this product. Thanks, you have a great product. J.P., Colorado PS – Before I used Premium fuel and now I’m using only mid-grade fuel and getting these kinds of results.

Hello AquaTune, I own an automotive repair center. Recently we had a customer whose vehicle would not pass emissions because it was smoking so severely that the emissions testing center would not even insert the probe into the tail-pipe. After installing an AquaTune unit on it, and allowing it to run for 45 minutes, all smoking came to an end. The vehicle was then taken back to the same testing facility and, in fact, the same people and they were absolutely astounded at the difference. The vehicle passed below standards and totally proved my skepticism wrong! I was also amazed at how it cleaned up the rings. I now plan on using this device to take to other shops and dismantling yards that sell used engines. Thanks for both myself and my customer, “ D“ Auto Service, Nevada

Dear people at AquaTune, I purchased one of your kits after a friend of mine recommended your product to me. He has two of them. I told you I would send you the results from using your product. I have a 1995 GMC Jimmy with a 4.3 Vortec engine that is lifted 7 inches over stock with 33x12.5 tires. I was getting 7-8 mpg. Since installing your system, I am now getting 14 mpg and can notice a big difference in the power! I am keeping up from the start with full size Yukon’s. I am very impressed with this system and have and will continue to advise anybody to try this system and you will be impressed too. Once again, thank you for a product that really does what it claims. Sincerely Yours, “Dale” B., Georgia (This vehicle is taken to truck shows and is utilizing the AquaThrust application)

Dear AquaTune, These are my results on using AquaTune on my vehicle. This is a 3.2 L V-6 1993 Isuzu Trooper. It weighs in around 5000 pounds, has 4-wheel drive with mud and snow tires, automatic. The final drive ratio is 4:57-1. Not the greatest truck in town. I use my truck in my janitorial business. Before AquaTune, I would only get around 15.5 mpg highway driving. Now it’s at an astounding almost 21mpg! Around town I was getting 12-13 mpg and now it averages around 16 mpg. With the unit set up for power, I was able to break both rear tires loose for the first time! It was quite a surprise. Before AquaTune, acceleration was lack-luster, at best. Now it is responding and moves when you want to. I now have no trouble merging with traffic! The seat-of-the-pants feel is great!! Carl S, Sunnyvale, California

To Nick @ AquaTune, I have tried everything I could think of in order to pass the emissions test, including installing new, after-market injectors, which brought my CO up way past acceptable rates at idle, and hydrocarbons were out of sight, both at mid-range and under load. The next step was to replace the CAT converter and EGR valve. Then I heard about the AquaTune system from one of your dealers, Todd Gossling, and decided to install it on my 1979 Datsun 280Z. This was better than spending one thousand dollars. I just want to report to let you know that it did go through the emissions very nicely with the AquaTune unit on there. I did not have to install the CAT converter or an EGR or anything else. It went through at 1/2% of CO and a couple hundred hydrocarbons at idle. Then 3/4% of CO and a couple of hundred hydrocarbons while under load. So, it worked very well. The car does seem to run better and I'm very satisfied and just wanted to let you know the results on that and there you go. Appreciate all your help and excellent product. M.W. - Phoenix, AZ

Dear AquaTune, Just a lengthy note and test results in how delighted I am with your product. Last year I put one of your units on my wife's 2000 Mitsubishi Montero and went from 16 mpg to 23 mpg highway miles. I was so happy with the results that I purchased a second unit for my 2003 Honda Element EX with 4-wheel drive with roof racks. I also have a trailer hitch and sometimes tow a trailer. This vehicle has an automatic transmission. The best that I have ever gotten, without the A/C on, at 65 mph, was 21 mpg. Here are the results, the best and the worst, since putting this unit on and having driven over 7,000 miles: 55 mph w/o A/C: Best - 35.5 mpg, Worst - 32.5 mpg, Average - 33 mpg; 60 mph w/o A/C: Best - 33 mpg, Worst - 30 mpg, Average - 32 mpg; 65 mph w/o A/C: Best - 32 mpg, Worst - 28.5 mpg, Average - 30 mpg; 70 mph w/o A/C: Best - 30 mpg, Worst - 26 mpg, Average - 28.4 mpg; 75 mph w/o A/C: Best - 26 mpg, Worst - 24 mpg, Average - 25 mpg. With the A/C on, the results were equally impressive: 55 mph - 33 mpg; 60 mph - 30 mpg, for over 600 miles! 65 mph - I went to Yosemite over the Grapevine (mountainous road), did 981 miles and averaged 28.2 mpg; 70 mph - 26 mpg; 75 mph - I got 24 mpg, going to Joshua Tree, CA and back. All these mileages tested out with the A/C on. These numbers are amazing!!! This is almost a 50% INCREASE OVER STOCK. I love it! The car is peppier and gets great mileage. What more could I want. Thank you so much. P.S. - ...I will recommend this to everyone I know. -Gary Henley

I had the system installed on my ‘86 BMW and got an astounding 38% increase in mileage and a dramatic increase in horsepower which is very evident going up hills. I was so impressed with this system that I had one installed on my ‘92 Chevy Blazer also. Got a very impressive 32% increase in fuel economy on this vehicle. My transmission doesn’t down-shift anymore in going over the mountains on my way to the coast. John K., West Linn, Oregon

My ‘87 Honda failed 3 smog tests. Even with an oil additive guaranteed to make it pass, it failed. Even with a new catalytic converter, it failed. It got ticketed and then impounded because I couldn’t get it registered. The judge wanted me to donate the car to charity. I put an AquaTune unit on, passed the smog test and have a very zippy car now! I am satisfied because I did not want to do engine work OR give it away. It used to get 26 mpg and now gets over 40 mpg... ! L.K. - California

Dear AquaTune, I’ve just got to tell you, after ordering two of your standard AquaTune kits, I had one of them installed on my ’91 Jeep Wrangler with the 4.0L fuel injected engine. This, as the mechanic says, is a very tired engine ‘cause it has over 200,000 miles on it and I tend to have a “lead foot”. Not only is the hp fantastic, my mileage jumped from 11 – 16mpg with my foot into it. Can’t help it, I love the hp increase. Now I’m upgrading my other vehicle to an AquaTunePLUS. I will certainly keep you informed on the results. Thanks, D.W., Nevada

Dear AquaTune, I started out as a very skeptical customer and I also took the liberty to call your distributor in California to ask him what their overall results were on my kind of vehicle. Because of the favorable report, I decided to order the AquaTune unit for my ’89 Toyota Celica, 1.8L engine. I used to burn a tank of gas per week. Going the same distance every single day as before, in other words, driving to work and back, traffic and all. You can imagine my excitement when after a week I was down only ½ tank of gas. I didn’t realize that this vehicle could run so smooth. And horsepower – lots of it! Love these results, terrific. Thank you, Hector C., California P.S. – I’ll be ordering a second unit for my Mazda MVP shortly.

Howdy AquaTune, I installed this AquaThrust unit on my ’68 Chevelle with the 327 engine and I'm running at least 40 more horsepower (feels like it! hard to tell), my engine sounds a little quieter, and I'm glad of that, because it was border line illegal with the higher lift cam over 3000 rpm. I picked up 1000 RPM more of a hard pull (5800 to 6800, had to shift, didn't want to break anything). Before, the engine's pull would drop off after 5800 rpm. What I could check for regarding HP was I dropped my, from a roll, 10 to 60 mph from around a little over 4 seconds as opposed from, a dead stop, 0 to 65 in around 3 seconds or a hair over, impressive, everything was happening so fast, even with 3.73 gears. I went from 1st, 2nd at 6800 to 7000 rpm's, to 6th and ZIP, I'm on the freeway. That got the old heart pumping. That's enough horsepower for me, I wanted mileage and looks like I got both. I'm going to check that with a stop watch one time to see exactly what it is, but that is a very close estimate. Gas mileage I don't know yet. I'll check it later, but I'm sure it's better. You can stand behind the car and not smell exhaust as bad as before. In fact, you can't smell much at all. Simple to install. Oh, you are supposed to run medium grade gas, not Premium. It will run better because it burns faster and more complete, also you increase the distributor advance 7 degrees more so you get a longer burn. You believe that....wow. The engine runs cooler and the engine oil is suppose to run 25 degrees cooler, which I believe. It runs on a Qt bottle of distilled water and 70% alcohol in a 50% - 50% mix. That good for 1 tank full. Should pay for itself with gas mileage increase. Thanks for reminding me about this system Jerry, you gave that push and I'm glad I did it. I thought all you Hot Rodders out there may want to know about an increase of horse power at a reasonable per dollar spent. You’re also helping the environment out at the same time for your children. Thanks, I achieved everything you folks promised and a whole lot more. E.D., California

Dear Nick, I have the unit installed horizontally so that the logo can be read on it. I did several good runs and my fuel economy showed an improvement of approx. 33%. (This is a straight 6, 3.3L '84 Holden Commodore VK which is the same as the GM Vauxhall in the UK)..I will be testing some more and hopefully generate some orders for you. I was a little disturbed that your competitor at HydroBoost is spreading his reports about your product as giving no improvement. I have tested his and other products and have gotten very little - at most - 10% gain. His product is a lot of fuss for nothing. In touch again soon, Luke, Australia

Dear AquaTune, I did not get the 30% better that you had estimated instead I got 32% better. What a neat system you have. Love it. The horsepower is great. I’ve been telling all my friends about this. Tom M. Portland, OR

Dear Ursula, I’ve just completed all the measurements on my Sunbeam Tiger (Ford 302, with a 4 barrel Holley carburetor), after the installation of the AquaTune system. The resu lts are really great! Horsepower without AquaTune: 269, Horsepower with the AquaTune: 306! Also, there is a big improvement in mileage but I didn’t make exact measurements because I do not care too much in this field. I made the measurements with my portable dyno (Gtech) but, most important, I feel the difference. The strange thing is that the engine goes better and better every day! Many thanks, Pavlos V., Athens, Greece

To Whom It May Concern: I want to let you know how extremely happy I am that I achieved everything that you promised when I installed my AquaTune system on my ’92 Ford Explorer with a 4.0L engine. Not only did I receive my 25% increase in fuel economy (mpg), I also received a very impressive horsepower gain. I would also like to tell you that prior to putting this system on, I used to have a serious blow-by problem. So much so that even my valve covers would leak oil from the excessive crank case pressure. This problem has now totally cleared up with this system, and no more leaking oil. I will be recommending your product to my friends. Thank you for such a fine product. Sincerely, Thomas E., Northern California

Hi Nick, Houston, we have lift off!!! Turned on the unit for the first time with a fill-up in Florence. Basically lacking the needed courage, I filled up with Plus (one step back from the Super I'd been running) and headed south down 101. At Winchester Bay there is a long hill south of town and as I started to climb I thought I'd do a "ping check" so, under load in 5th I stepped down and, not only did the ol' gal not rattle herself to death, it accelerated. Not neck breaking but picking up speed. Never would have done any better than hold steady speed before. This is exactly the seat of the pants kind of stuff I'm looking to document with a fairly tired motor (130k+). Thanks, B.P., Oregon (The vehicle in question is a 1970 Datsun 510 2.2L)

Dear AquaTune, Having been satisfied with your product and the 25% increase, for quite a while, I started studying the instruction sheet over again and by simply straightening out the placement of the processor so that the injection would go smooth and straight in and slightly shortening the line, is when my fuel economy really started going up on my ’04 Ford Freestar with the 4.2L V-6 OHV engine, I started out getting 14.7-15.1mpg in town driving and 19.3-20.2mpg on the highway. Now, however, I’m getting 20 to 20.7 mpg in town and on the highway 25 to 27.7 mpg at 65-75mph. Remember, too, that I drive with 4 Hankook HPW401 snow tires @ 42PSI, the year around! That is a 35-40% increase in my fuel economy. All this going up a 550 ft. climb in altitude & the hp is quite impressive, as well. Am I happy? Yes, otherwise I wouldn’t be writing this. S.L., New York

Hi Nick & Ursala, Installing an AquaTune on our SUV, a ’91 Toyota 4-Runner with the 3.0L engine, was the BEST thing Deb and I ever did. I was seriously considering getting rid of the bottom heavy slug until I installed the AquaTune! Installing AquaTune was like somebody cutting everything off the rear. This vehicle felt so much lighter. I was so impressed I purchased another unit for my ’96 Jeep Grand Cherokee, 4.0L engine and my sons ’93 Corsica LT with the 2.2L engine! Thank you all at AquaTune so much for this product. Deb and I are glad to become part of the solution. Thank you, Greg & Debbie, Arizona

Fantastic!! Nick, after you installed the system on my 2000 Winnebago that has the Ford V-10, I filled up the gas tank where it wouldn't take any more. I drove back to Newport, OR, 88 miles, I even had a head wind for about 20 miles, I don't know how much horsepower the engine gained, but it has to be a lot. I filled up again when I got back, it took 6.8 gal's, I tried to get more into the tank, but that is all it would take. I was getting 7.5 before and that was on I-5 cruising at 63 mph, on Hwy. 18 going up hills, having it kick out of overdrive I got 12.9 mpg. Thanks Nick, you have really got a winner. Thanks again...Ron R., Newport, OR

Dear gracious people at AquaTune, This is my second testimonial and I feel that you should know the extra fuel economy and hp I received out of your AquaTunePLUS system. I drive a ’95 Cadillac Deville with the 4.9L engine. Originally my mileage was 14mpg no matter what I did to improve it. With your standard AquaTune I immediately jumped to 22.9mpg, and I was ecstatic with that increase. However, I took the system off and gave it to my grandson for his Cadillac. The only difference in the two models is the color. I put the AquatunePlus on mine and I am now getting 37mpg on the straightaway! Uphill I am getting 35.2mpg. I also noticed that my transmission is not having to go into overdrive to go up the steep grades. What a fantastic product! The gas savings are phenomenal. Now I am going to order a downstream generator to add to my grandson’s car so that he will also have an AquaTunePlus. Thank you again, Frank U., Pennsylvania

Hello Nick at AquaTune, As you recall I recently purchased a second unit. This time it was the AquaTunePlus kit and installed it on our ’04 Subaru. Are you ready for this? The mileage went from 22mpg to 31.5mpg! Be assured I’ve been telling a lot of folks about this product. From your dedicated customer, B.H., New York

Attention Nick at AquaTune...Hi Nick, This system works GREAT! I have been running a 50/50 mix with Isopropyl Alcohol because of the cold weather. NO DETONATION. Since I am unable to advance the timing without the chip, I added a lower blower pulley that boosts 5 lbs. over stock which brings it to 14 lbs. total. Thanks for everything, -D.W. - Washington (This is on a '01 F-150 SUPERCHARGED V-8 truck!)

Hello AquaTune, As you well remember, I first ordered your AquaThrust system for my ’97 Honda CRV, 2.0L back in January of 2004 and thought I was getting really good results with it. I then decided to upgrade this system with the Downstream Hydrogen Generator, and all I can say is “Wow”! On my previous engine I was running a turbo-charged application. So I am very familiar with that type of performance. This system far exceeds that, it doesn’t damage the engine and, in fact, prolongs the engine life, and gives me fuel economy to boot. Not to mention, the oil temp is down by 25 degrees, just as you said it would be. Nice product, keep up the good work, Pete D., New York

Nick, I installed the system on my 2004 Chevy Tahoe with the 5.3L engine a few short months ago......WOW! My computer tells me over the last 3 months that my mileage went from 16.8mpg to 20.2 (you do the math). I only run distilled H20 50/50 mixture with Isopropyl alcohol as recommended and with today's fuel prices I am absolutely convinced that if this system works in my big, heavy SUV it will work for any make or model! Thank you Aquatune, and be assured I am spreading the word. -Joe C., Albany, New York

Nick, When I placed my order I told you that if this system would work I would definitely get back to you. Good or bad. Well, let me tell you, I am one happy customer! I put the AquaTune on my ’98 Ford Super-van, as you well know, this is a big box van that has the Triton V-10, 6.8L engine. I was getting 11.5mpg now I am getting a remarkable 21 mpg on the highway! The horsepower gain is absolutely phenomenal. Even the exhaust system sounds completely different. It’s amazing what you can find just searching the web. I am so thankful that I found your product. Be assured Nick, I show this system off a lot! Best regards, Michael B., Louisiana

Hi Nick & Ursula, Its been awhile since I met with you last summer and purchased the second Aquatune but I thought I would give you my 2 cents on how its doing. As you recall I traded in my old version of Aquatune which had been on my ' 93 Jimmy which has 230K miles, for the new version and put it on my ' 04 Chevy Blazer. I could feel the difference in power and so could my son. Well this Christmas we took it back "home" to Iowa and as usual we went up I-35 at the pace of about 85 mph (made it to NW Iowa in 12 hours). I had an extra half gallon of distilled water and a bottle of Isopropyl along as well. I found it used less water cruising on the freeway than it does in town. I usually go thru a tank of gas and 2 qts water for 300 miles in town driving. But going 85 mph we made it to Kansas on one tank of gas and averaged just short of 21 mpg. And the Aquatune still had about an inch left in it too. Now EPA estimate for my Blazer says 16 city / 20 mpg highway and they sure don't go 85 on the highway when they test. I usually average about 18.5 in town driving but then my right foot seems to be lead footed a lot! Love that power. And recently I had some warranty work done on the Blazer at the Chevy dealer and when they opened the hood they saw the Aquatune and asked if it really worked. Well you know me, I "schooled" them on it. And every chance I get at the gas pump I'm showing other SUV owners what they can do to get better mpg and power and give them your site web address. K.H., Arlington TX

Dear AquaTune, Forgive the quick note but I just had to tell you this system is awesome! Going back home it took 1/4 tank less fuel than it did coming down. Thanks again, S.L., Tacoma, Washington

Nick, As I suspected, after filling up my tires and finding a nice long, flat 20 mile stretch of highway (from Searchlight, NV to Boulder City, NV), keeping the car at 61 mph with the a/c off I was able to increase my average mpg to 49.7. My wife and I couldn't believe our eyes. The entire 251 mile trip gave me 34.7 mpg, which is great considering the elevation changes I was making 2500 to 3500 to 700 and back. Lots of strain on the little four banger. After 108 miles at 36.1 mpg, I burned 1600ml of water with 71 mph max, 4737 rpm max, and 50 mph avg. I almost wish I lived back East where there isn't so much mountain climbing. I'd be saving even more a fortune. I'm having a lot of fun with this test. Thanks again for your help. Sincerely, Nick D. (This gentleman was getting 28mpg to begin with on a 2000 Ford Focus, 2.0L Z-tec engine using the AquaTunePlus kit)

Dear AquaTune, Back in January I purchased two of your AquaTunePLUS kits with great hopes of improving the fuel economy on my ’00 Acura RL 3.5L. As I told you when I was placing this order that my mileage stunk. The average, at best, was only 20mpg. I am very, very happy to report that at last reading, I am now getting 32.5 mpg, and that was with a 30 mph headwind! This product does everything you say and much more! I will be installing the other one on my wife’s car as soon as I have the time. What a fantastic product you have. Be assured I’m telling everyone about this. Your very satisfied customer, Tom M., Kansas

To our friends at AquaTune, Once again, you’ve made us very happy campers. I bought a second AquaTunePLUS kit for my wife’s car, a ’04 Mitsubishi Lancer with a 2.0L engine, as a present for her. This wasn’t as easy of an installation as my other one but, well worth it! My wife absolutely loves it! She was getting 20mpg overall previously, with not exactly a light foot. Now, driving at 80-85 mph she’s getting 32+ mpg and in town 25+ mpg. The horsepower gain is incredible. She’s happy and this makes me very happy. Talk about a present that keeps on giving. Thanks again, D. B., Georgia

To the AquaTune folks, End of last month I bought two of your AquaTunePlus kits, one for my ’01 Chev. Tahoe with the 5.7L Vortec engine. The other was for my wife’s Suburban. This investment was well worth every penny! The first thing I experienced was the sharp increase in hp gains. The next thing I noticed was that I used to get 350 miles per tank of gas now I am getting 417, and that’s with my foot into it!! One of these days I will calculate my mileage while driving normally. I will keep you informed and I’m telling everyone I know about this terrific product. Thanks again, S. H., Arlington, TX

I ordered an AquaTune for my ’90 VW Vanagan Suncro with the 2.1L water-cooled engine and had my mechanic install it. Needless to say my mechanic was quite impressed with the results after this installation. When I came to pick up the vehicle he told me I gained every bit of 30% increase in hp. As he puts it, it definitely gave it some big “kahunas”. Of course, after driving it myself, I am in total agreement with him. This is why I am placing my second order today for an AquaTunePLUS for my ’90 Audi Quatro. Your happy customer in New Jersey, R. D.

Dear Nick, I installed your AquaTune system on my '68 Ford F100 pick-up that has a 390 engine and it really enhanced the performance. Under optimum driving conditions I achieved 27.6 mpg and normally had been only at 15 mpg. What a difference. Thanks for all your hard work in developing this invention! Regards, J.W. - South Carolina

Nick, Last night I went to the Cowboys game with my son. After the game as we were leaving the parking lot, I decided to "punch" it while pulling onto the freeway. Boy did it take off! 2nd gear usually gives me a solid "chirp" of the tires but, this time it screeched about 3 feet on 2nd gear shift (this is with an automatic)! On top of that, a great improvement in my mileage. K.H., Arlington, TX

Nick, The AquaTune Water Injection unit on my motor home increased the mileage approximately 30%. Because of that, my wife has decided to purchase one for her car. Thanks, M. McWhorter, Texas

Dear AquaTune, Just a quick note as to what my results were. I had put the AquaTune system on my 2000 Ford Taurus with a 3.0L DOHC engine and my mileage went from 22 mpg to 29 mpg in town and on the highway to 33.9 mpg. Phenomenal product. Thanks again, SL. New York

Dear AquaTune, I have an ’89 GMC 2500 converted van with a 350 V-8 engine. Before I installed your unit on this particular van, I was getting 16 mpg at the very best and having predetonation problems, which is why I was using premium fuel! I immediately jumped to over 20 mpg with low-octane fuel. Also, the increase in hp is fantastic. I am very pleased with your product. R.T., Florida

Hello AquaTune, I bought your AquaTune system for my ’89 Chevy Suburban, 5.7L, 4-wheel drive. This is the 1500 series. With this gas hog I was lucky to get 14 mpg on the highway. Now I am totally beyond myself because on my last trip I got a whopping 28 mpg! You can best believe I’ve been telling everyone about this product. D.H., South Dakota

To Whom It May Concern at AquaTune, Just thought I’d drop you an email about the AquaTune system I installed on my ’90 Chevy utility truck. This vehicle has a 5.7L 350 engine in it. At this point, this truck has over 423,000 mile on it. I installed a factory-crate motor on it at 276,500 miles. This gas-sucking monster was averaging only 15 mpg prior to installing the AquaTune system. Now, after driving over 30,000 miles with your system, I am averaging over 24.5 mpg. In my in-town driving it is 19.5 mpg. The truck has definitely more pulling power as I am going on uphill grades and doesn’t downshift like it used to. I consider this an incredible increase with your system. Because of my recommendation, friends have ordered from you also. R.B., Texas

Dear Nick @ AquaTune, I promised that I would get back to you with the results on my MGB Roadster as to results while racing on the club run to France. This is a grueling run throughout the UK. A leaking fuel pressure regulator in the engine bay ruined my records for the first part of the trip. Fuel was being pumped out all over the place. This was some 400 miles into the trip. I started the figures again, and extended the test to include two long journeys with a good mix of driving conditions. In France, the test included stop-start, short journey s, hard driving and inclines. On the route back to the UK and from the south coast back to Wales, the driving was sustained high speeds and in the last hour over mountainous and country roads. The subsequent return trip to the Midlands to extend the test was again sustained speeds and mountainous terrain. I was astonished at the increased pulling ability of the engine when the AquaTune unit was fitted. I have had so much fun with it using it on the performance setting that I haven't bothered with the economy setting. So the figures I quote perhaps could be improved, but who cares? I used straight distilled water for most of the test, but found that as you recommend, significant extra power can be obtained by adding Propanol. The mpg figures were not significantly affected either way with this 50% mix. The benefit to the hilly and mountainous driving is quite astounding. The car happily pulled up 10% inclines in fourth gear or third when bends are to be negotiated. Overdrive was not in of course, but the flexibility at all speeds was remarkable. Willingness and pulling power was noticeable and I may have a rolling road test one day. The car already has mild tuning with race-angled seats and valves, (hardened for unleaded use), polished inlet ports and stainless steel performance manifold and exhaust system. Electronic ignition is also fitted. I have tested the car's fuel efficiency over many years before the AquaTune unit was fitted, and when tuned properly it returned 27 mpg. Over 1,477.3 miles under the conditions described the roadster returned 33.87mpg, an improvement of 25.43%, which is very impressive for older technology. There is much interest by all who have seen it. I joked not when I offered to be an agent for you in the UK, or Spain, (we are buying a second property over there), I believe in the product, and I have the market connections in classic car world. I am well impressed and having fun - thank you very much. Best regards, Neil K. Perry.

Hi Nick and Ursula, Just a quick note to wish you well and to let you know that my gas mileage has increased from 9 mpg to 11.5 mpg on my truck, thanks to you. S.R., Salem, OR

Dear Nick and Ursula, My two AquaTune Systems work fantastic. My 96 Dodge Conversion Van 5.2 Liter (318) went from 15.5 to 19.6 at 70 mph, (pushing a lot of wind, not very aerodynamic) without a hint of sparknock, like I had before. The engine really pulls strong and feels like it gained a lot of horsepower. My van has 65,000 miles and my next Dodge was going to have a 360 5.9 liter in it, but honestly, it would not run any better (and I tow over 10,000 lbs. I am a little over the tow rating, I know, by about 4,000 lbs!) So I will stay with the 318 and AquaTune. I also installed AquaTune on our 27 Sea Ray 454 EFI Year 2000, and it really came alive. The mix I like to use is 50% distilled water and 50% rubbing alcohol (91%). Nick and Ursula, you folks really take care of your customers, and thanks for excellent answers to my many quest ions. WHAT A PRODUCT!! Larry Duchane, Bay City, MI

Dear AquaTune, We put one of your units on our 1980 Harley-Davidson. It ran so good we wanted before and after dyno reports and found that we had gained 4.5 hp and, in addition, 4.6 foot pounds of torque, also in addition to this, it greatly reduced the emissions. I was so excited with it that I put it on my 1983 GMC pickup w/454 and was amazed to find that I gained 5 more miles per gallon going from 9 mpg (at best) to a consistent 14 mpg, with a phenomenal increase in hp. And even with the lowest grade gasoline, no more pinging. Just a quick note to thank you again. I’m going to put a unit on all my rigs. Sincerely, Tom Norris / Boulder Ridge Masonry

Dear Ursula and Nick, I had come to you to have an AquaTune installed on my ‘93 Chev. Cavalier because, as a widow on a fixed income, I needed to stretch my gas budget as much as possible and also I needed assistance in passing the emissions test. After putting on the AquaTune, not only did I pass the emissions but, where I had been getting, at best, only 15-17 mpg overall mileage, now I get 26.2 mpg. Thank you so much!!! PJH, Hillsboro, OR

Hi Nick and Ursula – Well, I told you that if the system worked to my satisfaction that I would provide a testimonial, so here it is. I’m very pleased, in fact extremely pleased, and downright ‘stoked’ about the water injection system. My problem was pinging, and no matter what I did, and believe me I tried everything I could find, it seemed to have no effect. I could eliminate the pinging only if I severely retarded the timing but, then the overall performance suffered so badly that I could barely pull away from a stop. I found that for my car, it’s a 1979 MGB, it’s still best to run premium fuel, and straight distilled water. I know that some people mix the water with alcohol, and I have tried it myself but, for my car, water only has proven to be the best. I have gone to the next hotter plug, and I have found the optimum timing for all the variables. It took a while, lot’s of road testing but, now…wow! Before the water injection, about the best I could get before pinging started was only 2700 RPM’s…which is insanely low. But, now I can easily get to 3500 out of first, 4500 out of 2nd and, easily to 3500 or 4000 out of third! What a difference. I never track mileage on paper but, my wife and I take certain drives repeatedly, and I have a pretty good ‘feel’ for fuel consumption, and I would say that your estimate of 25% increase in fuel economy is accurate. Today, we drove round-trip from Oceanside to Cardiff and used very little gas, probably less than a quarter tank. Nick, I’m very pleased, and I’ll happily recommend this system to anyone.
