happens to mine all the time. I have checked everything. I think its the turbo intake hose with spiral wire inside and if not something to do with intake manifold design

maybe wastegate noise? when my car wasnt running full boost it would hiss really loudly as the wastegate was open most of the time. maybe a gasket is shot or something? try and get a friend to drive behind you and see if anything looks awry when its making the noise.
