I ran my car last year and it was the first time I ran a stick car down the track. Right out of the box I thought that turning off the T/C and launching at 2K would be best and I was right and turned a 14.8@94 mph, can't remember the reaction time but IIRC it was in the 2.3's. I wish you could completely turn off the system because even when its turned OFF, its still ON and it retards the timing still and applies the brakes. IMO the car has another 2-3ths in it!
