ok guys heres the deal. i need to just shut my EGR off for now. i was on a site that had a tune library and found some tunes for the LLY. to tune my truck with that tune does it only have to be for a 2005 or will a 2004 and 2006 lly tune work? also tuning a TCM for a stck tranny. will this help anything with some power increase until i can install my suncoast kit?
thank you
Mike
