i have a loud noise (sounds like a horn or supercharger) that i cant get rid off its when i come onto boost and around 4k rpm - 5k rpm

i have removed dump valve (blocked up on fmic)

checked all piping ( fmic )

checked vacume hoses (gauge to dump valve to inlet man) all fine and no holes

checked turbo play (before i had the car back together running)

could the noise me the plastic pipe that runs to the turbo under the manifold?

has any one had one leak before and what does it sound like?
as its driving me crazy!
