The change is not permanent. Simply cap off the intake and let the BV vent to atmosphere and see if this is up your alley. If you don't like it, simply revert back.
while I agree it would prob be a little annoying on DCT cars, it really shouldn't matter much as the valve only vents under positive pressure when the throttle plate closes.. You may get a fluttering while cruising but this can be alleviated by adjusting the BOV spring pressure. When the car isn't in boost it should act normal
