Mods are JB4 15 ohm, Mr5 intake, snow performance meth/water injection. 2 cm3 nozzles, one in each intake snorkel pre-filter, and a cm10 into a custom elbow.

It'll be easy to improve upon. Just going when it drops to below 50 degrees, and ordering my UR catless pipes should put me in the 11s if I can improve on my reaction time.

Has anybody here tried comparing times on a 2nd gear launch vs a 1st?
For me 2nd gear launch was good for a solid .05 to .075 off ET, but didn't affect traps much at all. The 60' is quicker from 1st, but the shift eats all that time and then some (at least on my car). Also wheelspin in 1st and the RPM needle flying like crazy to redline make it a tricky launch, I did finally master it but it took some time to get the shift right at the sweet spot (4.5krpm pull paddle, with it shifting ~6k). If you have wheelspin in 1st the auto trans logic is suspended and doesn't upshift so it will bounce the rev limiter.
