I just installed a ZZP stage 2 kit on my 06 lsj.


Put the 3.0 Pully with the #60 injectors, shorter belt.


After installation started my car and it instantly went into reduced power mode. Car ran extreamly bad, basically no acceleration. Check engine light came on and got a TPS performance (or something like that ) code. Doubble checked everything and all my connections. Everything was good.


The PCM that ZZP sent me was missing the tabs on the middle connector for the hold down.


I replaced the PCM with the Stock one. Car has troubble compensating for injectors, but no codes are thrown. TPS reads fine.


What should i do? Does this sound like a PCM problem or what?

So your using your stock PCM? You HAVE to use the PCM they sent you, its tuned for the injectors and pulley.

Think case relearn if installing a new PCM !!!!

Im using my Stock PCM now just to get me back home. Im not driving my car now. When i had the New Tuned PCM installed the car went into limp mode instantly. threw a TPS code.
