Default How much fluttering noise is normal vortech

Since I've been driving the car more I'm questioning the loud fluttering that happens a lot while cruising. From searching this seems to be compressor surge and possibly the bpv not set correctly? It happens under light acceleration and sometimes in-between upshifts. These aren't the best videos to hear it but it's all I have for now.
Vortech V3 and Tial QRJ not recirculated btw.
Best video so far

It sounds very similar to this but only while driving at low rpms like 2200 cruising, more of a whistle https://www.youtube.com/watch?v=KtReC1-rZtA
