Jus looking at both pcm tables on tb vs 0411, fuel injector pulse width and flow rates and voltage are same as a 4.8 i have in file so im very confident this is going to be doable. Yes different pcm but close to same yr. So if i get it done now ill let ya know if i blow it up or i need more than one tune. Considering i have a few pcm laying around and a bench harness even have couple spare engines i think i have parts covered.
