you dont need your rpm and speed limitter removed



My car may run 18s, but I can do your taxes in 10 seconds flat.
JBO lube - they would never have enough in stock and we'd never see RodimusPrime again

you dont need to raise the rev limit unless you have a built up drive train. which i doubt you dont have. you will end up breaking something.
and no need to raise the speed limit either. unless you are trapping 108 mph in the 1/4 drag strip.
and if you are street racing like a dumbass, i hope you kill yourself. and if you are not, then im sorry for the dumbass and kill yourself part



Im a Xbox 360 fanboy...and damn proud of it!!
