I think of it as a performance part, a safety item, not an emissions part.

Only thing one gains by removing it is the RPM's drop faster with throttle lift and maybe more or less exhaust ignition depending on ones AFR's and ignition function.

Slowing rpm drop might be an issue for some with a poorly functioning D-valve but on a Turbo it also helps keep the boost up between shifts.

In my opinion.

Speedy Squirrel,

Cool stats and pics.

As to sucking in air if vented, it is left attached to the area before the throttle body which is always pressurized by the turbo. If it was left attached to the area after the TB and vented to atmosphere it would not make much sense.
I understand. I'm referring to just disconnecting the upper manifold end and leaving it open. That is a big problem. I though that might have been what Mark Houghton was going to do.

Taking it off, reversing it, and using it as a BOV presents no hazard.
