How is BOV routed on this setup? What did you change?

BOV is integrated in intermediate throttle manifold on OEM 3.3 930 engine and is somewhat ambiguous when it comes to operating procedure.

Are you still using old integrated BOV aka "the clapper"? Are control hoses connected in same fashion as on old intercooler?

Reason I'm asking this is beacuse it sounds like your overboost switch is tripping on shifts, which usually happends when BOV is not operating correctly. Turbo still spins beacuse of inertia and tries to pack air into closed throttle, which trips the switch until turbo slows down a bit.
Thank you for your time,
