Also, Ive noticed when I pull up to the tree on the drag strip, with the 7AT, you can mash the brake and accel to about 2500-3k without wheel spin and you will get a nice little launch. Try with traction on and off for varied times. I lowered my time by about .2-.4 seconds by this method. Good luck!
