This valve vents to atmosphere (that's where the "whoosh" comes from). On a MAF/MAP-metered engine like the Civic 1.5T, air the engine has already measured is dumped instead of recirculated. That can cause a rich stumble or stall when you lift off, and it can trigger a check-engine light. A tune is recommended to run this valve properly.
