No need to flame other vendors... I havent had a bit of problem out of my zzp pcm, however.. i wouldnt call it that now, due to all the tuning I have done with it.

Any vendor product can have issues, its how one handles business that makes them profitable and recommended.

I would say STB as well, but if you dont have an FWI intake, get one... I am for go fast mods ... maybe a DIY shift kit?
