Well that's great we all waited and waited for gm stage 1 tune now its here and its a lean tune prone to knocking? Are u kidding me? Could it be dealer installed error that was made? Maybe bad batch of gas? Maybe somerthing that present in engine before tune? Did anyone think of goin back to the dealer that installed it? Or maybe contacting gm directly? I mean this is not a fifty dollar part with minor consequences, were talking engine and power destroying knock here
And knock isnt just power destorying.....

DI is a different animal. Try running a LSJ or any other SMPEFI forced induction motor at 14.0 A/F at WOT and see what happens LOL.
Lucky you. Mine slips quite a bit at 400+ wtrq.

I had it for quite awhile, then I burned the clutch really good and it must've cleaned a layer of glaze off or something. It holds like a beast now Even 5th WOT it holds tight!

Maybe in a few thousand miles mine will hold. My traction control came on in third this morning.

Now that's awesome! That's because of all that cold weather we are having.

Immediately, it was VERY bad!! The pedal just dropped to the floor after the 2nd gear burnout, I just went fuuuucckkkkk.... stuck at the track now
I pulled it off to the side and let it sit for an hour with the hood open, then started it and drove it easy around the pits. Then did some runs and ever since it's been holding awesome!!! Im sure it's only a matter of time before it starts slipping again tho!

I put Hess 93 in it. I always do. But I just filled up again today with like 1/4 of a tank left. So, I will report back and see it if does it again.
But I ordered the Kiwi Wifi, (it runs off the OBD-II Port), and I can data log on there, and see knock retard.
And Term, I want your tune sooo bad! But then I would probably have to buy a damn clutch & flywheel because I want lots of power, and then I would have to pay you also.
Your my number # 1 choice! And you will definately be able to tune my car. :

The only thing I experience was little lag on a very cold night at 20 F in NC, but after about 20 minutes of driving my car was able to push 20 psi between 2000-3000rpms easily. I haven't experience any knocking yet with GMStage 1 or any clutch issues in the last five days of installment, but little lag on a cold night hitting 16-17 psi. Not going to keep trying to run my car to the ground just to make sure my psi hits 20 because I'm fixing to dyno the car on Saturday at National Speed to get results with Torque and Hp. I'll post the results when completed.

I think I was running a bad batch of gas... It hasn't knocked since that one tank, and it's still been cold (which it was those nights) and that's it.
The Kiwi Wifi will get a full review & it's own thread sometime very soon. It's awesome! But I don't think it can read knock... I have to explore it more!
