thats nice if you can get 15.1's but that really doesn't mean JACK! maybe you have a fast track (yes i know EVERYONE claims they run at a slow track, so don't throw that at me) If you want to compare driving skills, get on the same track, same day. Everything else is just talk. I love how everyone compares dyno numbers and track numbers, ever think that different track, different dyno = different times?!?!?
