To answer your question truly.. It really all depends on HP and Traction, if your pushing 300+whp with slicks your better off IMO starting in 1st only because youll grab traction a bunch quicker..
If your pushing 300+ w/0 slicks, some people find it better to launch from 2nd because you'll catch quicker.
It's really personal prefrence.. whatever you believe will make you make a better time.
