Looks like too much power to the RDU, may have overpowered the clutch packs, even if for just that instant at launch. Could have damaged the driveshaft in the process, if you feel vibration in the passenger cabin while driving. I would check the trans fluid also, a quart additional seems too much, I thought a pint was recommended.
Traction control has a role to play while moving. If sudden changes in throttle coincide with changes in direction, you can experience momentary power loss.
Most people will not BB higher than 2,500 rpm for a launch, tuned or untuned. Were you in Neutral when you hit 4,000 rpm?
