From what I have run over the years I always trouble tuning a flexible flyer. Here is what I would try if I was helping some one at the track. First step would be to ad a pound of tire pressure and tighten the compression on the right two clicks and tighten rebound on the left two. Then see what happens. Get some one to video the leave and see how bad the tire is wrapping up. That will tell you alot about your tire pressure and sidewall choices. A couple extra pounds and some help from the shocks to control the speed things happen can make a big change. Now what have you got in the front? How do you leave the line? Trans brake and two step of foot brake? Also hit can be worked with converter choice.
