Hello!!
Newbie here. Been tuning for only a few months. We are a salvage yard and I typically do simple tunes such as removing VATS etc from our donor engines.
We have a 2008 STS-V with the supercharged Northstar engine. Running an E67 pcm. Car starts but instantly runs on reduced power mode with no throttle response. Spec'd out all wiring at the TB, PEDAL AND PCM. Even tried tuning another PCM, same issues.
I can rev engine once if I do so immediately after clearing codes.
CODES ARE P1516 P2122 P2127
Here is my question.......is there anything I can attempt to alter in the tune to keep it from going into reduced power mode? The car has active braking etc and because its an accident car, my theory is that the reduced power mode may be due to an issue in the ABS/TCS .
Any help appreciated!!!! Thanks!
