Your bov only blows off extra air. When ur boosting and u let off the as, the throttle body will close. All the air that was going towards the TB now has to go in the opposite direction back towards ur turbo‥ this is known as turbo flutter, which will in theory want to cause ur compressor blades to turn inthe other direction. Having a BOV will blow off all the excess air. This is known to extend the life of ur turbo. Also, sometimes not having a bov can throw off the ecu because of the already metered air.
