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.
