Check and flex the pipe looking for signs of interior damage. Something is stopping the airflow causing the turbo to suck it flat.
How can the turbo suck the pipe to the manifold flat?

How old is the air filter? Have you tried with the pipe from the air cleaner disconnected?
There are a few reasons why it does that:
-dirty air filter
-siezing turbo(along with damaged compressor wheel fins)
-blocked intercooler.
I was figthing with this for a long time, ended up replacing the turbo, as it was using too much oil recently:
Shaft was probably siezing, too much force needed to turn it. Problem was showing up especially on hot days with high load(AC on) and overtaking.
Stock turbo is on the limit of it's output and efficiency over 3000 RPM, if it gets a little bit worn, strange things happen.
Upgrading it for TD04-15T should solve the problem.
That account for sucking the hose flat, engine sucking against a blocked intercooler.Well she went back together and ran spot on put my psi box back on after a run and no problems now guess the intercooler was choked up with crap
