Is the T56 form a 03-04 cobra ? I have a 99 2V with a t-56 and 3.73 gears and it was difficult to get decent 60' times with the car. I went with a 4.30 gear and went from 1.9 to 1.6-1.7 60' times easily.
U need meth injection I run this on my tbird vortech t trim if u want more details on the setup pm me

Your 60 is hurting you but your mph is no where near what a car with 430rwhp should be trapping. You should be in the 115-119 range easy. My guess is that something is amiss with the car.
I noticed that you were running 15 lbs of air pressure. My experience has been at least with 17" drag radials that they like more air pressure. I was at the track last Friday and with 30lbs I ran a 1.701 and a 1.67 60'. Just something to try the next time you are at the track.
i think ur are right bc at 18psi i got 2.01 and with 15psi 2.089
