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 have had the tuner now for a couple weeks and it has impressed me so far. I have only used it on the 87 octane and I'd just Ed for my bigger tires, but it has gave me better throttle response, power, and increased my gas by 2 mores mpg. I plan on running 91 octane and using the tune for it in a couple weeks and hope it does even more.
