Plugged it in and it did the tuning. Noticed change in power and mpg immediately.

Have a 2013 Sierra crew cab 4x4, it ran good but with the Superchips programmer it now runs great! When I step on it the truck almost jumps. Maybe a slight boost in MPG. Highly recommend if you're looking for a performance boost.

Was looking to firm up my transmission shift points and disable the Active fuel Management system, This unit allows that to happen. I wish the instructions were a bit more specific as to what every setting can and will do, but I guess I'll figure it all out eventually. The performance tune is a noticeable difference from your stock tune but again I wish I had more details about the tune itself.
