Hello Nick at AquaTune, Well, you made a believer out of me. I told you I'd kiss my wife if this system would work. And I did! I put your AquaTune system on my 8 cyl. '95 Cadillac DeVille. I love cars that are in good working order. My mileage went from 14 mpg in town to 22.9 mpg. It seems to be getting better and better as I continue driving. I'm so excited about these results that I've told my grandsons about it and they're planning on ordering a system for their cars shortly. Your service and your support is excellent!
