Attention Nick at AquaTune, 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 Tritan 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!
