Anyone experience noisy acceleration from BOV / Charge Pipe upgrade?

Not sure that's where my top-end acceleration noise is coming from. BOV is seemingly functioning properly (sounds correct when off throttle). Noise began following my N54 JB4 500 hp pkg. install. Car is standard trans (not experiencing this noise on my auto). More likely a noisy pulley?

Did you install DCI?

If you mean dual cone intake, yes.

The air intakes make some noise and you can hear the turbos more with intakes as well.
That’s more of an air suction/whistling noise.

Are you experiencing that? Or a different noise?
Did you install the Down pipes too?
