The MBC can be placed in line with the APC solenoid, and can be used to reduce the wastegate creep. To preserve the APC knock control capability the MBC needs to be set to a pressure lower than that of the peak controlled to by the APC itself, to allow some reduction in the boost pressure if required.
On my car I'm using a pressure relief valve in line with the boost signal to the APC solenoid. This performs the same function of preventing a pressure going to the wastegate until really necessary.
