Tried searching and failed so does anyone know the key words to this one? Anyway has anyone got the ZZP LSJ PCM or does anyone know if it is worth buying? Just checked it out on ZZP's website. Sounds like a winner but I would really appreciate some feed back.

This little green fish thanks you for your wisdom and insight.

 

Get a custom tune for your car via Trifecta/HPT etc. The ZZP Canned tunes and any other canned tunes are really conservative and you can get more out of your car than that. You might even me able to drop to a 2.9 on your GM Stage 2 injectors.

I think you also need to do a crankcase relearn with those canned tunes too, i may be wrong tho

 

I didn't but in some cases I've heard people needing it. Seems like a crapshoot.

Yeah, im getting the ZZP tune only because i need my car to drive. Its my DD and i dont have access to HPTuners/Dyno right away. But hopefully by spring break i'll get rid of the horrid tune. Actually better, gives me time to get my meth kit and get tuned for meth

and btw... there is PLENTY of info on this. You didnt search very well...

 

zzp has the best most safest canned tune out of everyone, trifecta, intense, ottp, gm and whoever else i missed. you will need a crank releard 9 times out of 10. that can be done at the dealer or someone with a tech 2 scanner or hp tuner.

 

I have the zzp tune for my 42's and 2.9 and its a good tune. So far no problems. Daily driveability is like stock with a bit more power.

I had the ottp tune for 42's and it just wouldnt idle right and it would hicup once in a while but that might have been due to me never getting a crank case relearn done. However, the ottp tune would just destroy the tires in 1st and 2nd, the zzp tune doesnt do this w/ the 50% boost reduction and 2nd doesnt spin as much either. Take it for what its worth...

 

i bought the zzp pcm before they changed it so you could specify your injectors. Basically just got it to open the rev and boost limiter
