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?

 

sounds like you may need a case relearn with the new PCM

 

dont drive your car on those mods untuned

 

How do you do a case relearn? Sorry this is my first time doing anything like this to my car. I was figuring since they were sending me a tuned PCM and needed my VIN that it would pretty much just be a plug and play kinda thing.

 

You need to bring it to a dealer to get it done or find someone with HPTuners to do it, do you have something to read the code? Interceptor etc.
