Default low boost levels, sounds of air leaking on excel (hot engine) and spudders low rpms?

I don't have a VAG at hand and I'm leaving for Jersey late tonight but I would like to get this resolved b4 I leave or at least for when I get back. I have not found an visible leaks, vac hoses look good, most are silicone. I checked intake and hose connections twice, top to bottom, but I don't have a pressure tester. Engine spudder only happens when the engine gets hot and I'm begining to excel. The air leak sound comes when the enigine is warm or I'm excellerating. My exhaust has picked up a squeak when it move but it doesn't sounds like an exhaust leak. Any ideas could help. I can't see a boost leak causing the engine to bog when its hot but who knows.

Just go visually inspect all the vac hoses that are coming off the intake mani.

Default Inspect ALL hoses coming off intake manifold. Pay attention in particular...

...at where there are bends in the hoses. Mine cracked on the inside of a 90 degree elbow.
