Two suggestions - First your wasting the dual intake if your not taking off your grill. It appears you have an aftermarket one, and may be more difficult to remove. The removal is good for a tenth at the very least.
Second - keep trying to dial in your tune. 15.0 on the top of 2nd gear and the 15.1 in the middle of 3rd on your datalog can't be good. My best runs have been around 12.2-12.5 across the board. Your rpms and shifts look to be spot on.
Good luck next time out. BTW, that 60' is good for an 11 sec pass.
