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!!


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.

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,


Hello Folks, Just had something I figured you might be interested in hearing. I recently installed an aquatune on my '79 Olds Cutlass with a '73 350 Rocket V-8. The power increase was awesome, part throttle torque hugely increased, and the fuel economy improved (I'm not sure how much yet. . . I've been enjoying the power increase a little too much). Anyways, I think the aquatune saved my motor though. . . I had a massive oil leak coming from under the (aftermarket) intake I put on the engine, so I pulled it off again and 
replaced the gaskets (with help from a friend). In the process of putting it all back together, we somehow forgot to tighten the heater hose down. On the test drive it blew off when I hit WOT and 30mph in 1st gear, covering the windshield in coolant. For some incomprehensible, stupid reason, I didn't bother to check the coolant level and simply re-attached the hose. Shortly afterward, I installed the aquatune. I kept thinking my car was running hot but for some reason didn't think to check the coolant level. Anyways, to make a long story short, I had the "hot" light come on and soon found that the radiator had very little coolant in it. I'm fairly certain that had I not had the combustion-cooling aquatune system on, I would have burned the engine up. But I just put some water in the radiator and went on my way, without a problem since. I'll get back to you as soon as I get some fuel economy numbers.Thanks for a great product,

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,

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,

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!!

Hi Nick, Just wanted you to know we installed the system on a 2001 Grand Am with a 2.4L engine. We started out with 18.9 mpg now we're up to 37 mpg. What an awesome system! We found the customer was ecstatic, to say the least.

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 ga soline, no more pinging. Just a quick note to thank you again. I'm going to put a unit on all my rigs. Sincerely,
