Got one, from Magnacharger, lol.
Running the 112H on the 112 tune and it eems pretty good. No KR at all and timing at 18* at WOT. The AFR hasnt been checked yet.

I know. I didn't just go out and beat on the car. I also talked to the GM engineer at Magnacharger. He told me not only was the tune going to be fat but I could add timing as I have 93 octane available and he sets the tunes up for 91.:)

18 deg though is a shit load of timing for a 122 setup , would be looking more at 14 deg myself

Acyually it is a 112H. I run 18-19* on my truck and dont see any KR and the AFR is 11.5-11.8. On the dyno I was up to 22* but just wasnt making anymore power so the tuner lowered it.
The GM engineer told me to ADD a couple of degrees if I wanted becasue 18* was conservative on 93 octane. I'm only making 6-8psi.
I do understand your concerns though. I dont want to pop #7...again:doh2: Been there, done that.
