Thread: overkill tune

I bought the car with what i thought was a stock pulley. It actually is a 3.4" So the torque app data i collected was with a 3.4" and not the 3.8" i thought. Mainly i was monitoring knock retard and at WOT the car was between 1 and 3 never saw anything higher.
I was told that even a stock GTP will see those numbers (i told everyone i was running a stock pulley).

They already run rich enough and run plenty of timing to keep the motor happy. If you needed anything it's likely code related or you want some transmission parameters changed.
