Default Turbo sounds

I have a 2019 WRX and after installing all these parts I noticed a strange sound coming from the car. It sounds like the flutter of bov but before that on deceleration or releasing gas it makes a gobble sound and was unsure what it could be. Any ideas? Thanks in advance.

Mods listed: with a base tune on car.
TurboXS j-pipe
Cobb Big SF+
Cobb AP
Perrin turbo inlet mount
Grimmspeed bov
Grimmspeed ebcs
Perrin charge pipe

Grimmspeed doesnt make bpvs so first step is to get the correct modifications list for the car.

Check for leaks that's what it sounds like.
