Porsche 0 to 60 times with triptronic?

[AZ UFO]

Are you pushing the gas down far enough and fast enough to engage the kickdown botton on the floor?
If you are in 2nd at a light and you smash the gas to the floor the kickdown button will engage and drop to first and you are gone, also if you engage the kickdown in almost any gear at a normal speed it will downshift 2 gears for passing speed.
