First of all I was impressed with how quick it arrived, the experience in using it!I after installing it and driving it I was totally impressed with the acceleration especially from 20 mph onward, the truck acted like it had a blower on it, and when I hooked up my toyhauler which was the main reason for getting the chip, I was very impressed by how it seemed like my truck doesn't have to work as hard pulling,didn't help mileage empty or pulling I have 01 GMC 6.0 200600

It was very easy to install and I am very satisfied with the difference that I have noticed in performance and increased miles per gallon. I drive a 2006 GMC, 2500 HD, crew cab, with Duramax 6.6liter and am getting about 10% better MPH.
