i was looking at the zzp pcm, i dont know to much about tuning. I just wanted something simple to remove the speed limiter and raised shift points. I also noticed i need to run 91 premium fuel, that dosent really bother me. i really only have a catback and cai. Is zzp a good way to go?, i was reading some other threads and nobody seems to like them. Or can anyone recommend a really good PCM like zzp's for around the same price range?
thanx
