E38/LS2/4L80E... Need HELP finding the culprit for ETC closure at launch

[85mcss]

As the title states, I can't seem to figure out what's causing my TB to close at launch. Seems like it dumps timing and ETC like TQ Management but i feel like torque management is essentially turned off in the tune.

I haven't been able to decipher whether or not the Virtual Torque tables will cause this or not but that's my next move once I get the Beta Suite installed to solve the virtual torque edit ability software issue. I had a colleague with HPTuners bump the MAP table up by 1.2 but that didn't seem to change the behavior of the TB. The more I look at the log, I may have an issue with PE enable too late and some AFR fluctuation associated with that.

Any other ideas?

Try disabling Stall Tq Management.
Set [TCM] 5410/5411 pair to 8100/8000 RPM.

I agree.

Other than that.. 28 degrees of timing is far too much especially that low RPM. The fueling is super lean. Be careful
