Boosted brz hissing noise

I never noticed this before but whenever i accelerate i hear a hissing noise but once i remove my foot off the gas the bov goes off and the hissing stops. Is that turbo spool? Just never noticed it before

It's probably just the turbo. Can you provide an example of the sound? It could be a boost leak at a clamp, but unlikely.
I'm sure that it's just the turbo spooling up.

Turbo surge or whatever it's called?

Yeah that's probably when your turbo starts making more pressure than you need and it starts to dump the excess.
