Have you been drinking?
Well done on not being one of the talkers and actually getting out there!!! Regarding the above comment, taking 0.269sec off of your 60 foot time will have the effect of taking more like 0.5 - 0.6 secs off of your ET. Having said that, it's a great start. There are people on this forum that are running low 12's that because of a 2.2 60' time, can't take advantage of their extra horsepower.
Try different things to get the most out of your car. Try running 20psi in your rear tyres to aid in the launch, change gears just before 7krpm and have fun.
Let us know how you go and good luck.
