Used it with afe cold air, mbrp exhast system as i was told to do and idle too low, called hypertech talked to a tech, he said something wrong with truck and the programmer doesnt have the capability to change gear settings or idle speeds. But when i first plugged this into truck, it did come up but i didn't know idle would be this low ( 500 ) so i reprog. to stock then went back to regular on prog.and this time the gear settings and speed did not show up, that was when i called him.

Truck is a lot more fun to drive now. Throttle is more responsive, holds gears longer under full throttle, and shifts do feel firmer. When getting on the gas after a turn, the truck seems to be in the right gear and accelerates better. Overall I am very happy with it.
