Hit Man X said:Yeah also I used to own a '99 NBS, it was a turd. Those had many, many PCM problems. Jared on here (99silver5.3) swapped in an '02 PCM in place of his '99 PCM and despite the Battery light being on his truck runs WAY better.
Usually they have False KR and other problems like low and slow timing advance tables too. My '01 when stock would run circles around my mild mod'd '99. That's how vast the difference is between them!
It wouldn't suprise me if TqMgt tables are different between the 1/2 ton and 3/4 ton but I'd like to see if the entire PCM setup is actually different for the timing area.
Do post up that EFI Live log when you get it with the TPS and Timing, I'm anxious to know if I'm crazy or not! :anitoof:
Chris99GMC said:My 99 is a complete turd as well. The engine is completely stong and flawless and I have a brand new built tranny.... The TM simply reems this truck. I doubt swapping a newer year PCM would be good for the truck, or the correct way to do it. A simple tune on any year PCM will make a world of difference on these motors. I am going to be putting either a PCM 4 less tune, or LS! edit in my truck when the gears and locker go in.
