I read thru your other threads. Did you have "Chris" reflash your system? Was he trying to compensate for the undersized injectors(23 lb)? Was any work done with the timing curves? Another far out thought would be something messing with the flexplate/flywheel reluctor.
Some specs on your build might help? I have a 2000 with a Russ P motor and it runs great!
The tune came well after I sized up the injectors. I believe Chris did give me 6 degrees or so of advanced timing, but honestly I pretty much just let him do his thing and didn't take notes. And he's a hard man to reach... Regardless, issue continues with a new PCM.
