I dont know if other gm trucks done this but mine will not power brake to save your life. when trying the rpm's stay a little under 2k. dose this have something to do with the traction control and when i do get it to spin as soon as it starts it will shift into second. i was wondering if allen can get rid of tcs so i can burn a little rubber.

I guess I am missing this in your post, but do you have a tune now or not? I am guessing no, unless it is not a nelson performance tune. Anyway get with Melissa from the board, or just call them and give them your specs and CC info. you will be buying new tires in no time.Originally Posted by SIERRA SS

If Its Awd It Wont Power Brake
The tune will help you power brake, but you'll never be able to spin those wheels.
The tune will help launching but it will never burn out.
Your brakes and AWD and the small stall converter is keeping you from going over 2K, that is about where the factory converter will stall to.
It may go up a little higher once abuse/TM/Timing are modified.

Mine won't burn out but it will spin the LF and RR tire if you brake stall it to only 1100-1200 RPM (no higher!) then hammer it.
