Are you planning on running the PCM ZZP ships you without any changes? Not sure if “Custom tune by ZZP” meant you’re driving out there for dyno/tuning time, or if you’re going to run a shipped PCM.
Relaying my recent experience- I had major issues with the PCM ZZP sent me with my SS M90 kit for my Monte Carlo- the MAF was scaled really, really rich and the car would barely hold idle. PE was tuned pretty rich too, and I had a decent amount of smoke out of the tailpipes when WOT.
I totally understand why they ship it that way (hard to detonate/blow your motor when you’re that rich), but a little tweaking with HP Tuners went a LONG way with how the car drives. They’re turbo kit PCM’s might be dialed in better. Does Ed or someone else up your way have a tuner? It’s probably worth having one on standbye in case you have any PCM-related startup issues after the install. I will say that the ZZP 1.0 I ran in my Regal for a good while was amazingly close to being dialed in for a canned tune.
I will be running the tune ZZP puts together for me for the new Maf and everything else added. Hopes are that it will run well with the tune they give me. I am not sure if Ed has a tuner, but I know ZZP dyno tuned his current setup. After getting everything up an running I will be looking for a dyno tune come spring.
