Turbo sounds like a supercharger

Just when pushing hard the turbo suddenly sounds like a supercharger. Anyone had this happen or anything like it. I’ll post a video on my IG and link it.

Sure it’s the turbo and not the differential? It whines very loudly when hot.

Found the issue, my APR PEX intake failed and my turbo was slowly eating it. They say it was over tightened but my mechanic and I both know that was not the case. You can’t clamp down on plastic. It was only snug we made sure of it. Anyway lesson learned. Every other company uses metal for the inlet pipe except APR perhaps they understood something about heat transfer that APR didn’t. I’m shocked to be honest I have lots of respect for them as a tuner but now I’m not so sure.
