One word: Experience
First time I ran, my light sucked and so did my run, a 16.7. Every time since then I have run, I have improved. I have heard many say it is 60-70% driver and the rest is the car.
While its true you are probably due for a performance tune -up at 45k, run a few more times before you drop some serious cash. Perfect your launches and get your shifts down as I think that is where clot can be gained or lost.
