I think your wastegate is stuck closed, so once you reach boost, you continue to build it while your BOV continues to vent it. This turbo "surge", if thats what it is, could destroy your engine.
That's not how a BOV works.. and if the BOV was open then there wouldn't be turbo surge. The BOV has a spring that keeps it closed under vacuum. When the throttle closes, the pressure in the intake pipes is higher than the vacuum in the manifold so it pushes it open. Turbo surge would kill the turbo, not really the engine.. unless the turbo completely failed.
