If it’s a constant bird chirp it’s gotta be an accessory. If it was more of a squeal I’d tell you to start checking exhaust manifold don’t take a big leak there to sound like a belt squeal every time your on the throttle.
Definitely bird chirp, it’s not related to boost pressure/exhaust at all

Although I do have one turbo clamp to replace but that’s a different animal
