For those of you who say their car does not have this problem at all, I ask you to try this for me. That is only if you are not afraid of driving your car hard :

From a standing start attempt a 4000+ rpm launch. This should result in moderate/severe tire spin. Launch hard enough that the revs shoot up to redline quickly with very little change in vehicle speed (ie. spinning the rear tires pretty hard). Do not let the vehicle speed catch up to the rpms by banging the limiter, etc. As soon as the rpms reach over 8000, attempt a quick and firm shift into 2nd gear to continue the burnout/launch.

This is where I have experienced the problem in my car; it only seems to happen when wheel-spin is present. I observed this during some timed 0-60 runs where I was experimenting with launch technique. Let me know what your results are.
