Burn out issues

As far as burn out procedures it's always been the same. Back up into water box, (on all 3 front street tire cars, blip the throttle to wet the tires, (except for street tires which get a dry burn out) step on brakes hard, engage line lock, 2nd gear burn out in 2 automatic trans cars
With the torqueflite, which I assume you are using, try starting your burnout in 2nd gear and shift immediately to 3rd gear for the rest of the burnout. I used to burnout in 2nd gear but got a lot better results with shifting to 3rd. I also agree that you need to measure and see if your axle is not square to the frame.
