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.
Allen will fix you right up. Give him a call.
could you before you got the tune?
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.Quote:

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.
Some years have a table in the computer which you can adjust to do some type of powerbraking. This is separate from the traction control. I know my 00 tahoe doesn't have it but I believe we changed it in a 03 or 04 6.0L truck.
