im not the expert here but a dv releases the built up turbo pressure when you close the throttle.unused turbo pressure hits a closed butterfly and got no where to go so backs up to the turbo where the blades chop the air causing chatter and stalls the turbo. dv releases this pressure so turbo doesnt get stalled by back pressure.
