Im in the process of purchasing a 99 Silverado. I know the 99-00 PCMs had some issues. A friend of mine has his old PCM from his 01 or 02 hes going to let me have.
Im currious if I can overwrite his VIN with mine, or if I need to find someone with a TECH2?
Also his was a 3/4 ton with the 4l80e, and mine will have the 4l60 for now. Is this something I can just overwrite with a stock 4.8 tune?
My main issue is the VIN.
I tried the search feature, but was still confused.
