Tun off the trac/vdim and turn on the ect. When it's time to go just mash the gas and let the car do the rest. You won't have any problem beating the TL. People are easily running 13.4 to 13.7 in the 1/4 mile using this method.
Running with 1/4 tank of gas, and removing the spare tire and anything you have stored in the trunk, etc. also helps a little.
