black smoke is a sign of overfueling. This is either due to too much fuel being pumped in or, more commonly, too little air. I'd be checking turbo hoses for signs or splitting, coming off colapsing or delaminating. I'd also be checking the air filter is clean and still in situ.

Ho yeh, check your hose from the air filter box to the turbo, this hose has an internal membrane, when sucking air, this membrane, if not in good condition, will collapse and block the air substantially...

good test is just to take it off and drive around a bit without it, carefull where you drive though, you dont want anything going into the turbo... or just get a plastic hose of some sort and stick on the turbo.
