BOV leak?

I have begun hearing the "woosh" sound from the turbo before shifting gears. I'll get to around 3k rpm and i will start to hear a steady woosh sound until after i shift again. Honestly, I'm a noob when it comes to turbos. Any help is greatly appreciated!

Is your car stock or did you replace your stock BPV for a BOV? We need to know your mod list.

It is stock except for a K&N air filter in the stock airbox. The dealer replaced the gasket to the downpipe 8 months ago. I havent noticed this sound until the other day. I was just driving it and it seems like it happens everytime i let off the gas too. Thanks for your reply!

It shouldn't that loud outside as it is in the cabin. But, that's the BPV recirculating the air back into the intake. Its normal.
