Ok, here is a launch before transmission and vb change( notice nice little flair between 2-3 shift)

The car has 90/10 culverts upfront
Sway was still connected
9 way adjustable Rancho's out back
SS springs with 3.55 gears
Tires were 275/60/15 at 22psi of pressure
It just looks lazy off the line.

This is the best it has done
