Superchips review

Reviewed By Charles S (Greenfield, WI) Reviewed for a 2004 GMC C/K 2500 —8/4/2012 2:30 PM

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.
