Default high pitch whistling noise coming from engine compartment

under hard acceleration past 2000 rpm up to 5000 rpm. Doesn,t sound like it's a turbo but I guess it's possible. Maybe the air intake. Any suggestions?

Default sounds like a boost leak

check TBB,intake tract clamps (and F-hose if you have one)
