12.66@111.9MPH with a 2.2 60' time. I'm running the Pilot Sports but I get sideways if I go full throttle under 3rd gear (or just sit there). Need some DR's.
In my old ZR1 (1990 w/ headers & chip) I managed a 13.01@113.06MPH w/ a 2.xx 60' times on bald Pilot Sports (times slips are at home, I'll add them later <g>
