The pressure switch cuts off at 1.1bar, if you are experiencing overboost then the switch would activate. Overboost is a very common by product of many aftrermarket exhaust systems due to changes in pressure differential and poorly designed waste gate plumbing. Defeat the switch and see where your boost level is. Obviously be ready to get off the throttle if it goes to the moon.
