Hey guys, Im planning an engine swap on my 2005 silverado 4.3 2wd. I have a 2002 5.3 I will be beefing up a bit. My question is am I able to load a tune from the '02 5.3 pcm onto the '05 4.3 pcm? Ive done a fair bit of googling but I see many mixed answers. Any help for a noob would be appreciated.
