Before you pull the TQ check the secondary butterfly opening, they should only open around 80%. You can also bend the tab on the air door to fine tune secondary. I would try decreasing air door opening.
Yeah I have been around the block a few times with thermoquads. Bending the door "changes the a/f" though I have found it just changes the number on a/f meter and never adds up to anything on the slip. I have learned to leave the air door where the car goes the most mph, and adjust the a/f with jets and metering rods.
I tried launching anywhere from 1100 to 3800rpm. Best time was walking it off idle. Its amazing how alittle traction changes the characteristics of a car... on the street it really drives pretty darn good.
