I ordered a custom tune online from allen nelson for my 04 silverado 5.3 4x4, i specified that i wanted 80% of torque management removed, i didnt specify anything on abuse mode as the tuning form didnt mention it, does anyone know if he disables it with his tunes?, im asking because i thought abuse mode had to do with off the line punch and holding it in first gear, and it doesnt want to burn rubber when i punch it, it just goes, that could be normal though as i am running all terrain tires, and when i put it in first gear it shifts automaticly to second when i get up above 30

 

My abuse mode is gone, and it still switches to 2nd gear after 30 if im not hitting the gas too much.

What other mods are done to your truck?

 

IF YOUR RUNNING SOME BIG HEAVY TIRES YOUR TORQUE MAY NOT BE ABLE TO OVERCOME THE TRACTION OF THE TIRES

 

Mine has 285/70s, and it doesn't want to spin em either. Mine shifts at 6100, and 50 with 3.73s. I think they are to soft, and wide(9.5") to lose traction on dry pavement. They squeal, but don't spin, it's actually kind of weird. Oh yea, 0 abuse mode, 0 torque management.

 

I just have a cai, and exhaust along with the tune, my tires are pretty heavy and aggressive, and it just depends on where im at as to if they will spin on takeoff.
