Looking at that chart again, you are in closed loop, meaning
14.7:1 mixture, while at a MAP in the 90s. Hello, ping. Why
is PE not coming in? Locked out by TPS perhaps, the TPS
enable may need to come down. I don't like how drive-by-wire
cars swing the TPS independently of what you -think- your
foot is telling it. Maybe you'd be better off getting ahold of
whatever maps throttle position and make it "what I said,
dammit!" instead of "what GM thought desired torque might
be, times a bit of fudgery".
If you want to be in closed loop then you'll have to pull out
more timing, but I'm figuring anything over 25% throttle
probably means play time.

I hope I get the parts to fix this brand new tranny soon too, spend 2 grand on a new tranny and I still have to do work to it to make it work right, hate fixing other peoples mistakes
So now the car is sitting again

Hopefully she'll be running right by friday.
Parts should be here today. You get your issues solved yet?

Just got back from the dyno this morning. Did some WOT AFR tuning and think she's ready to rock.
