Hi, I found some info in old threads about this issue- but all the ones that said "file attached" had none, maybe because of post age?? I have a 99 2dr Tahoe with a lq4 6.0 out of an 04' 2500HD. The PCM is from the donor truck. I have the wiring hooked up correctly- matching circuit numbers/ wire colors. I need the correct PWM table?? I am hoping some kind soul may have this, and be willing to share please?
