Hey did I meet you at the daytona meet? also I think I ran that night too.
Did you miss gears? let off before red line? any engine problems? My best run that night was 15.365, bone stock.
Just practice a lil more at driving, you can get it into the 15's. I know the first time I ran I ranged from 16.4 to 15.9. Then again, that was summer time.
