with some custom tuning you may be able to drop the time, but probably not 1 whole second without getting nitrous or a supercharger. The dissapointing thing about the n/a is that it's already engineered to pretty high standards in many aspects, screwing with the timing or replacing the ignition or computer is almost totally useless. Unlike a tt, you can;t just crank up the boost or replace the chip and get instant power. It takes a lot of r&d and dyno testing. I would suggest more displacement and built internals with an ecu modification to bring your redline up safely.
