Just throwing out my issues for anyone that might be listening, but I hope everything is going OK for you now!
It is definitely IAT related, and I'm not sure what happens first... either the car falls flat, then the code hits, or the car falls flat because of the code. It's too hard to tell. But it's definitely high IAT's, 4000+ RPM for like 2 seconds and poof.... code is thrown. Even in the winter I've parked it long enough to get some heat soak and went out and floored it and haven't had an issue. All I can think is that the IAT factors are pulling too much timing.
Post your current tune file.
so this happens when IAT is high, this is causing cylair calculation to be low, this may be tripping one of the sanity tables, now if we can figure out exactly what.
I did add a new cam back in October http://www.tickperformance.com/tick-...r-ls2-engines/
The "heartbeat" Eaton blower has the IAT/MAP all in one unit that is mounted in the back of the blower. I'm not sure that heat soak is all the problem, maybe it's just the hot air.

I added some timing and then made a log.
