Hi im new to this forum but iv just got a turbo 2000 uk and when under full throttle in any gear the boost either holds back at 0.5 or goes to around 0.7 in the next gear. However sometimes it goes just above 1 bar and i get boost cut :\ how can i get a steady 0.9 as all my car is standard. (tryed ecu reset and cleabed bs) thanks matt
