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.

this is the real deal.if you are skeptical don't be. then again if you don't like more horse power and torque this may not be for you.Plus you leave it plugged in for track times and data enquiries.totally change the way my Mustang automatic shifts,so much authority.all joking aside could not be any happier with this programmer!
