On the rollers we couldn't get the car to boost past 1.2 bar no matter what we done. Mapper suspects its due to a Dodgey wastegate spring. Its a brand new turbosmart wastegate but I can't seem to find any springs for them for sale. Large spring is 47mm in diameter and am looking for a 1.2 bar spring. Any help lads? I tryed messaging eBay sells to see if they would measure there spring sizes but they didn't see. To bothered. Cheers shaun
