Hey, I've been reading threads here for a while, but I just got the need to join.

I'm just east of Charlotte NC and we own a few 99-07 GM full size trucks, repair a bunch of them for customers, and do some LS Swaps. I'm a complete noob when it comes to PCM tuning, but I'm trying to learn, and I have some spare pcm's here in case I screw it up. I'm going to try to keep my stupid questions to a minimum.
