Then come back.

Canned PCM's suck...get a real tune. And I'm not talking dyno stuff either.

Good luck ever hearing form the guy to get the Overkill.

I had a ZZP PCM. I liked everything it did for me. Higher shift points, higher rpm, fans stay on for a few minutes after cut off. If you're close to a good tuner get a tune, I'm a long ways away from anyone.

In car tune is better but not always a option. I'm happy with my Overkill PCM. Actually going to send it back to get retuned. Only issue is WIll some times takes a bit to email you back but that's expected since this is more of a side gig and not his main squeeze.

Everyone seems to forget. Unless you've done something to your pcm you're running a canned tune from gm.

Lucky you.

Wil is a kinda tough to get a hold of and I waited 3 weeks for my OverKill PCM, the $145 was well worth it, it's like night and day difference from the stock PCM to Overkill.

Best though is the in car tune. Good luck with whatever route you take.
