I have a 1998 K1500 Sub, with the 5.7 small block. I was going to send it off so I can eliminate some of the things I want to get rid of. It's my understanding that they code out certain things. Do you offer that service as well? You are certainly closer than NY and I'd rather keep my dollars here in the south. At least I don't have to send it to china.What year pcm i may can help and im closer
