Coupe and Sedan are only about 100lbs different. I've seen Coupes of the same year get taken by Sedans, and Vice Versa... It really depends on the car, and the driver.

Your launch needs improving... Get your 60' times down to 2.1 and your ET's should improve by 2 tenths.... Maybe more without a passenger..

If you have a factory PCM you will benefit by shifting manually. Put it in 2 to start and manually shift to 3 at 93MPH. Since your trap speeds are around that, you will be shifting right in the traps. Just don't hit the rev limiter.
If you have a reprogrammed PCM, just put it in 3 and go.

What scan tool did you get????
