Kinda nervous-blitz ss BOV flutter/woosh

[mr.nismo.]

I've had my sr swap in for a year now and my blitz ss BOV has always made a fast " choo-choo-choo" and it's 100% atmosphere. I thought that's how it sounded since my wide band reads a rich condition every time it goes off. However I was on YouTube and saw every SS BOV woosh, no flutter. I know they're are two different springs that it can come with so I assume I have the stiffer one, however since it's technically it's doing it's job I should be fine? Wait. If I rev it up enough (I have an ARC induction box) I can see the filter flex back and forth a little with the BOV as it goes off. That's compressor surge then isn't it. Fuck
