Last year i was running 15.1's on a 91 Tune and i got a bunch of tips from Ry also.

A couple of them would be:
#1 Turn Off TCS
#2 Turn Radio Off
#3 Turn A/C Off
#4 Powerbrake til about 3000rpm's
#5 Like they said dont man. shift just putting it in drive works the best.
#6 When you are about to take off; when the yellow lights starting going, release the brake and floor it on when the 3rd yellow light comes on not when it hits green. It takes a few 1/10's of a second for the car to react so you will have better reaction time.

Our race track is almost open, i cant wait only 2 more weeks YAY.

 

A couple more things i forgot.

-Take out all the extra wait from the car, including spare tire if you can get it out for the night.
-Only have 1/4-1/3 of a tank of gas since you wont need a full tank and it will be less weight from less gas the tank is holding.
-Tires are filled toaround 35psi.

 

actuaally I think you want to lower your PSI on your back tires to like 25.

Does this thread have room for manual launch techniques as well?

 

If your not too experienced at racing then you dont want to lower the tire pressure too far, you want to get used to it and drop it as you get more comfortable.
