I want to get a tune for my 06 SS. On my previous truck I had a wait4me tune, and it was pretty good. I still have the stock pcm from my 5.3, but I just talked to Jessy and he said the 6.0 is different. Does anyone know where I can get a stock 6.0 pcm, or know what the hell i can do with my old 5.3 pcm?
