High Pitched Whistle Under WOT

I’ve had my M235 for a couple months now and I have been noticing a high pitched whistle/rattle during hard acceleration. It’s not normal turbo sounds but almost like an intake leak or something. It sounds like it’s originating from the driver side and I cannot hear it during normal acceleration.

Question is is the whistle/rattle normal? If it’s not has anyone had it diagnosed and repaired?
