The stock convertor stall speed in most cars is less than 2000rpm. You might overpower the brakes when doing that, or at least warp them a little.

An NHRA Stock Eliminator racer I used to work with at RP told me a secret to auto trans launches, and that is to launch the car at 400-500 RPMs LESS than the stall speed. If you have a Street Fighter 2200-2500 Convertor that launches your particular set-up at 2300rpm, foot brake it to 1900. The few hundred RPM's "shocks" the convertor and results in harder, more consistent launches. If you have a stock convertor that launches your car at 1800, footbrake it to 1400. It worked wonders for my 12-second '77 Camaro.

Also, when you line up at the starting line, try to put your front tires directly in line with the darkest rubber strips that are already there from previous slick cars (That's called "running in the groove"). That'll help your traction, even if you don't think you need it.
