You could check for a vacuum leak. Check the hose that connect to the throttle body as well as the brake booster. I think it does also have a line that connects directly to the intake manifold, yuh could check that also.

A vacuum leak can cause the engine to "run rich" which would case the black smoke.

you have a vented blow off on your car?

[BASS MONSTERS!!!!!!]

this is caused by either a damaged air flow or faulty wireing to the airflow, black smoke is a result of to much gas being dumped into the chambers not enough air to copensate for it so it burns black..................
