mine ran a few 13.6's but the clutch was slipping so it was quite hard to get the launch right it was td04 @1bar 230.5 on a jam p&p ecu with bald r888 tyres partially stripped with bucket seats I recon with an lsd a decent clutch and an ebc setup properly so that the boost didn't come in so aggressive and just spin the wheels I would have broke 12's eventually but that might just be me dreaming lol
