i just went to the track last week and ran a 14.9 at 95mph (not happy with that time, should be lower). i have a auto with stock 2.73's, not ideal for the track. u probely have the same crappy gears. 3.73's or 4.10's would help a lot in a auto.
you should be able to power brake higher then 1500rpm's at the track, cause of the amount of rubber thats on it. i was able to power brake to about 2100rpm's without spinning the tires, and a little chirp when i launched. when u see the third yellow light let off the brake and mass the gas!
manualy shift the car yourself (AKA AOD shuffle), at about 4400 to 4900 rpms. and give the AOD time to shift cause it will take a few hundred rpms to shift, so it will really be like 4600 to 5100. letting the AOD do all the work will net in higher ET's, so u need to help it out.
hope that helps a little bit, good luck!
