um bitchn 7, my gtx does 14.6, with exhaust, pod filter, air box, front mounted intercooler in new zealand, i dont see hows urs gets going that quick as simply they arent that fast

post up the time slips

u know considering the gtx does 15.9 standard

my cars way more modified than urs and it wont do those times, either urs has a brand new engine, ur a loser and dont know what ur talking about or it has some mods u dont know about it wont get near the 13's

my mate has a GTX with 170k on it a 3inch exhaust and thats it......
boost is up to about 12 - 13psi and he runs 14 flat.....but his gearbox did blow up - u prob need to go harder? how r u launching?
