Has anybody tried to launch an XLR. I tried to but the car would not peel out like the STS. I took off the traction control but it seems that engind would not give enough power to the wheels for it to spin out. Th engine started to overheat.

Yep, it's a dog off the line. Do you know the trick to remove TC and stabilitrack?

Hold down the TC button and watch the read out below the speedo. When iit shows......... TC & stabilitrack off, .............let go and you might find you have a car you can drive the way a car is meant to be driven.
