The CBV is a valve that connects the intake pre-compressor to the intake post-compressor. Its also called a blow-off valve among other things. It's there to prevent compressor surge, and vent excess boost back into the intake. It is different than the wastegate.

The problem sounds like the wastegate to me. This is a valve and actuator (actuated by intake pressure) that lets exhaust gasses pass around the turbine and into the exhaust, so their energy does not contribute to spooling the turbo and creating more boost. This is the primary means of controlling boost, and if you're overboosting, then this is the first place to look.
