5.3 with LS1 computer question.
Blew up my LS1, and i'm swapping my 5.3 in right now. Have a few different threads about it.
Anyways, the car is a 1998 TA and i'm putting in an 03 5.3. My question is, will the car even crank with the LS1 tune and the 5.3? If it does would it run like total crap? I mean if it'll crank I can probably take it somewhere to have it tuned, but other than that I don't have anyway to get the car to have it tuned.
