shift questions.....traction control?????

just curious, i'm new to this computer, injected stuff.... going to track this weekend and was just wondering with my 6-speeed if times will be better on or off traction control, and has anyone shifted without the clutch against the rev limiter with success???? we used to do that all the time with our old school muncies and super t=10's and such..... running nitto 555's and an all around performance spring/suspension setup. appreciate any ideas
thanks

Traction control will kill your 60Ft times.

As for "speed shifting" I have no idea, It is probably possible, but I have never tried.

Turn off your traction control
