Hey guys can I swap in a V8 from a 2009 colorado with the E67 PCM? And swap in a T56? Apparently I can program the E67 to communicate with my 04 BCM. My question is what tune do I start with? What factory vehicles used an E67 and T56, I can't seem to find any? Is it possible to delete the auto transmission programming, and ad the T56 programming using HP tunner? Or can I take a 5cyl Colorado with a manual transmission, and modify its tune my by adding in more injectors, and coils, then set the parametrized to match the V8 tune? How many credits do I need to purchase to make this possible? Thanks for any help! -Jamie

My donor truck is a 2004 Colorado with the 2.8L atlas 4cyl, and a MA5 5spd manual transmission.
