high pitched nosies are normally boost leak related. have you checked all ya pipes.

Could this cause loss of power between 3k to4k RPM? The noise I hear feels like air blowing high pitch but my pressure gauge (positioned on the hot pipe) doesn’t show loss of boost. What could it be? We removed the clamp on the efi for convenience purpose and put a screw clamp instead. Yesterday I checked if it was tight enough but it was OK. Also I think that this wouldn’t change the wastegate work in the turbo. I checked the BOV send screwed in a little bit the spring pre-compression I got nothing changed.
