I was thinking boost leak too. That'd be audible as a hissing sound when boost came on.
Is there an intercooler involved, and could that be damaged?
I was wondering what was causing the lack of power in mine and what the hiss was when I put my foot down - had a proper look at the hoses and sure enough the top hose from turbo to inlet was split underneath where the clamp went round, really hard to see at first but thanks to reading this I managed to find it. Fitted a new hose today and all good - but $130 for a 100mm bit of hose!!!
