96 Dodge Conversion Van 5.2 Liter

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!!
