The diverter valve (DV) is a pathway for boost when it is not being used by your engine. Whenever the throttle body is closed, like during shifts or deceleration, the boost needs an escape route. If the boost cannot escape during these times, it can back up and cause shocks to the turbo. A Blow Off Valve (BOV) performs the same task as a DV, but instead of returning the boosted air back into the intake, it vents it the the atmosphere.
