Return the dual port and buy a "Plumb-Back" BOV from Turbosmart. You won't get the sound, but it will work properly and you will get back your gas mileage and have a better performing BOV.

Factory turbos all come with bypass valves now, and blow-off valves often lead to problems as they vent metered air to atmosphere.
I doubt there is a performance gain in replacing the factory valve. But I would definitely install a turbosmart valve in its "plumb-back" configuration.
