Cool vid. A few things I took away from that, I'm assuming that was a motor pass, it seemed like the shifts were a little short, now when spraying it should turn a few more RPMs before shifting so you may not want to change it. I just want to point out that it could improve your times a little on a motor pass, the one two shift especially. The other thing I noticed is the car didn't leave straight, do you have to steer it to the right often? Possibly soem adjustments to be made there. I also feel more consistant when I continue my burnout as I move forward for a few seconds.
Just my two cents, take it with a grain of salt. I'm sure this will start something from the know it alls, and I try not to be that way, but maybe a few of the things I do might work for you, maybe not.
