Default headphone users: what is the bov related noise?

I was watching some of my videos and noticed a strange sound immediately after getting off throttle during a pull.

It sounds like a couple kick drums and then bov whoosh.
Sound occurs at right at end of the pull 0:15

cobb 20g and GFB 50/50 100% vent

Well my tuner actually told me every singular GFB BOV they have seen has leaked and/or failed at some point so I would get rid of that asap personally.

In regard to the noise, it sounds like the BPV vented early to me.

My tuner recommends turbosmart products over GFB due to leaking issues so I think you should be fine once you swap over. How long have u had the GFB? From what I understand, the leaks tend to get worse over time.
