I trapped about 115-116 on the average when I 431/419 to the wheels. On a cold day I hit 121 once. My friends 05 gt with a few bolt ons and exhaust ran 12.88 at 108, that same day. The track was only 550' and it was so cold and dry that we had negative DA numbers. But like I said I still averaged 115-116 at my regular track which is 1200' I have ran where the DA numbers where in the 3700's and still manage 114. I think you should let it hang out to 6200 rpm since you have the SC.

Yea air gets a lil thinner at 6000ft . But yea I didnt take tire diameter into account also, that makes a lil more sense. I have my rev limiter set to 6200 so I usually try to shift around 6k
