check your i/c and hoses could be leaking or cracked loose hoses

Take the intake hose off the turbo and see if the impeller spins good and is tight. Also check for the usual as old man river suggested.

You haven't cracked the EGR pipe, or warped the manifold.
You'll be blowing clouds of black smoke if you have popped a boost hose off.
What year do you drive??

He was throwing a "grenade" joke at ya mate. It's a thing you learn to cop with 3L's. I get it all the time. LOL
On a serious note mate, does the "squeal" you get rise up and down in pitch with turbo spooling up and down? I have a slightly similar thing on my CRD. I don't lose power or boost though unless it's really hot.
Read my post here, is it anything like that?

I haven't fixed mine yet, as I still don't know 100% what it is. If you read further into that thread, I mentioned that I had it put on the dyno under a bit of load while the mechanics had their heads under the hood trying to figure out what it is. We looked all over the engine. IC isn't leaking as there isn't oil anywhere. The mechanic seems to think mine one is a mechanical noise of sorts, something inside the snail maybe. He also thinks if it was an EGR or exhaust leak it would be quiet obvious as there would be an exhaust stain wherever the leak is, but there is none anywhere that can be seen.
And as I said above, I don't loose power and/or boost as much as you do. My boost jumps up to 16-17 no dramas.
