You just found your gremlin.  That hose is collapsing under the suction
of the turbo trying to get enough air to provide 6+ psi of boost to an
engine turning more than 4000rpms.

BTETFI.  (been there, experienced that, fixed it)

One option that I've heard of people doing is to replace that hose with
a piece of metal pipe and just use some short sections of rubber hose
and clamps to connect it to the intake spout and down by the turbo.
