Hey guys. I just ordered a complete ZZP SS M90 kit for my 2001 Pontiac Grand Prix GT, along with stock GTP injectors. I didn't order the ZZP PCM, as I have heard horror stories about it. Everyone talks about the DHP PCM, but I am unsure which one to get, as I will no longer have a true L36, but not a L67 either. I prefer to just get an unlocked canned tune for now, and eventually get it dyno tuned once I have completed every modification I want. What should I do?

Thanks!
