Its all in your launch bro, I have some mods to my shee as-well, and i launch out of the hole pretty dam good, All my 4poker buddies cant understand why they cant even beat me out of the hole, never mind once we hit 3-4 gear.
Practice you launches when your by yourself and i promise you'll get good.
I went from a +2 swinger 15/41 gearing back to a stock swinger/ stock gearing
20" razr in the rear.
Is you rear shock stock?
are you running race gas bc thats alot of compression..
