“I have gone from 5.5 mpg to 7.2 mpg.”

I had the EngineMaxx and Revelation installed and it has turned my 2005 Cat Acert into a completely different truck. I have had to learn how to drive it all over again. It sounds completely different and shifts completely different. I have gone from 5.5 mpg to 7.2 mpg. People don’t believe me when I tell them this until I let them see it on my computer. I love the extra response, power and most of all the extra money that I can send back home to my wife!

I run a 2006 Acert 550 HP and I had a For Sale sign on my truck because I couldn’t get my mileage over 4 mpg. Continue reading…

“[W]e were able to save a total of $13,167.60 on fuel costs…”

I had to write a short letter to thank you, Jim and Dean for the great product you have come out with in the EngineMaxx. As you remember, we had this device installed on one of our trucks some time ago. We have kept very accurate track of what this device has done for us. And we wanted to let you know what it has done and is continuing to do for us everyday. Continue reading…
