Hey all new here.

2017 320i with JB4 tune, CTS blow off valve, injen intake, and ER charge pipe on the way.

I just installed my intake and getting turbo flutters at lower RPMs when I let off the gas. At mid-higher RPM 3000+ I get the BOV to open and some flutters. This only happens in sport mode.

When I'm in Park and rev it up, I ONLY hear the BOV and the intake swoosh. Almost no flutter

In comfort, I just get some flutter but it's not as loud.

Your thoughts?

I've searched all around and get so many different answers so I'm still looking for advice.
