Wot it is I bought the car with blown head gaskets wich I took the engine out heads off pressure tested valves reground skimmed 5 plate heavy duty gaskets new tensioners roller bearings and put back together started straight up no probs sounds ace but when took for mot it seems to spool up then just before it boosts it dumps the pressure so I am a bit puzzled with not having a kot of experience with thease engines I am looking for a bit of guidance I am quite a competent person with most engines but with twin turbo never seen as many vac pipes nite mare so woundering if a pipe could be a starting point hopefuly I will be coming to sheffield 8 sept do ya think someone could point me in the right way as I am hopeing to join you with remapping on the 18 of sept all being well yoh wont be able to miss miss me at sheff I will be a all black legacy gtb tt apart from I am 6ft 18 stone and slightly grey hair ( but not a fat 18 stone) lol I may even wear a pink flower I my lapel cheers ash if it as to go garage then so be it but it may be something simple dont know
