Having problems reaching 1bar of boost on my HI setting. Doesn't seem to shift past 0.85/.87 with the foot down. Trying to find a reason for this, i have noticed that the solenoid doesn't have the Blanking plug fitted? Could this be a reason? Its been set-up properly. I'm thinking that its got to be a vacuum leak somewhere. Dumpvalve not sealed properly? Boost lines not sealed properly? FMIC hoses not tight enough?
