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

This product do what they claim it does. I just had a little issue first when trying to install it but after contacting Superchips directly they had an update that fix the issue. Truck is now running a lot better.

I bought this so that I could hopefully improve fuel mileage while towing my 14,000 lb trailer. After 800 towing miles I have not seen any change from stock. I do see less downshift on grades which means more HP.
