Great run, as Bill pointed out 14.7 was the best time I've ever seen posted for a 6 spd.
If you have any friends with Crossfires, see if they will loan you their front tires to put on the back of your car for a few runs. The smaller diameter should effectivly give you about a 3.45 gear ratio, and less rotating mass to overcome.
Just make sure you dissconect the center wire on your traction control.
It sits right in front of your battery.

Push your mirrors inward, and you can even go so far as to put your whindshield wipers in a vertical position, on your windshield and pull the fuse. I'd suggest pulling the fuse on your rear spoiler as well. It's in the fuse box in front of the steering wheel. Less parasitic drag.
Good Luck
