No codes. If I come to a stop and take off again it gives me 37bls of boost through every gear and problem doesn't start till I am up to speed for a few minutes.Starting to wonder if this is fuel related?

sounds to me like maybe its going into some kind of derate. Check engine state with insite while pulling a hill.

Does the engine have factory programming in it? - or does it have a de-mandate tune in ti? - and if so, who did it?
