I have a 2005 Chevy Silverado 2500HD with an LQ4 with a sloppy stage2, VSR 7875 Billet, deka 80LB injectors and I also have a 3000RPM stall convertor in a 4l80e. It really doesnt matter what I do this thing will not do a burnout itll pretty much just hold it at 3000RPM and not doing anything while on the brakes. Ive messed with the Torque Management settings, made sure brake torque management was disabled, I really dont know what to do now. Ive done burnouts in heavy duty trucks like these and even seen others do them with just a cam or even just a tune so im doubting it being the brakes actually holding the tires. Ill attach a tune and log while trying to do a burnout, yes i know some of my TM settings are weird.

My AFR is weird because I have it hooked up through my AC and forgot to unplug my AC but my AFR was good during the log.
