'20 1LE A10 2nd gear launch

Please provide some details on how to adjust the TCM to allow for a launch in 2nd gear (in manual mode).

Can you even adjust the tune on the '20 TCMs? I thought after '19 they couldn't unlock them anymore.

I also doubt GM employees will tell you how to adjust anything in the tune of the car.

Yea, I just discovered the T93 TCM is locked, and I'm assuming my '20 has one. I'll bet the Russians who hacked the US Treasury could unlock it though.
