How to improve 60' times? in IROC R/T

I am running Goodyear F1's at 25PSI in right front and 28PSI in the left. I just can't seem to get good 60' times with my G-tech. 2.37-2.42 is the norm. I have tried dumping the clutch to slipping it out. I did manage a 2.92 once. Mike

Ive found the G-tech not accurate when compared to track times. Plus if your trying to do this on a street, forget it, the ground is dirty and inconsistent. Go to a track a see what happens.
Thanks Wallace, I was trying to fine tune it before I go to the track. Slicks a must? it seems that way to me after watching other front drives lose traction.

No, slicks are not a must but are definitely better. Iam cutting 1.9's with 300 treadwear cheap radials on my Charger. But it's now an auto and that helps as well. One thing I have found is that shocking the tires/drivetrain in any way kills traction on a FWD. I go for smooth and progressive power application during the launch.
Brian, my best times come when I slip the clutch out but I feel I could be quicker if I dumped the clutch at a high RPM. I don't usually get wheel spin until the boost hits- if they both spin I move out pretty good but if only one spins I might as well just ease up on it and enjoy the scenery. How are you guy's doing burnouts in the burnout area?

I don't do a burnout. I just do a very short tire clean off. I also have an adjustable home made 2 stage boost control that is triggered by the speed sensor that limits the boost in 1st gear that helps keep the tires planted until I build enough speed that when the higher boost does hit it won't blow the tires away.
