I need to be upfront, my question is NOT HOW TO REMOVE Torque Management. I already know how to dial it back.
I need to understand what TM is monitoring that causes it to pull timing. I want to log those same PIDs and see how TM is working.
BACKGROUND: I have a 2001 Chevy Tahoe, believe it's a P01 Gen III Computer (possibly P59?). I have a built 4L60E and 6.0L with mild cam. I'm using baseline 5.3L tune, updating VE and MAF calibration. During some of my data runs it's pulling as much as 30 degrees of timing. I have also attached my latest tune "03 RUn 05 Final". It is setup to run / tune VE. Running MAF / MAP doesn't seem to make a difference in TM behavior.

If there's a table that will let you configure how much timing (or throttle, if DBW) gets removed to cause a reduction in torque, you could try zeroing it out.
I'll admit I haven't tried it, but hopefully that would mean that when the PCM tries to reduce torque, it won't be able to.
Sorry I made a typo. I already know how to dial back torque management. Goat Rope Garage has some tutorials on Youtube among others I've fiddled with. However, doesn't get into nuts and bolts behind Torque Management, just how to dial it back. I want to make an informed decision instead of blindly turning it back. I don't know what PIDs to monitor so I can make an informed decision on Torque Management.
Definitely AC torque management. You can see the ramp in and ramp out even in that pic, notice how two spark reductions are always right next to each other... Compressor on, compressor off.
Maslic briefly explains Torque management in his transmission tutorial excerpted from his complete downloadable manual (transmission tuning chapter 6 -HP tuners and EFI live).. Chapter six has more detail in the manual.

I certainly wish I could help. It is so refreshing to see an intelligent and useful question nowadays. Unfortunately, I, like most people, just get rid of whatever degree of torque management we wish without actually understanding what triggers it. I hope someone has good answers for you.
HP Tuners which PIDs to monitor Torque Mgmt?
