Are you going to Cecil? Good luck! Be sure to let us know how you do. BTW....Capitol is open this Sunday (12-5 pm). It'll probably packed, but I'm going anyway.
Regarding your question: Are you running F1's? If so, I usually drop my pressure to 28 lbs and only do a quick clean off spin (or drive around the water if possible). My best 60's (1.9x's on F1's)have come by just launching off idle. I tried stallin' it to 1000-1500 rpms, and that made it worse.
Everyone has there own method based on their local track prep...but I've found that method works best for me (at Capital).
