Well from what I understand, black smoke is just unburned fuel, usually from running a little rich. Nothing to be alarmed about... A tune would fix it if it bothers you.

Actually the black smoke could be due to the new exhaust you got put in. When i put a borla exhaust w/ xpipe on my vette it smoked for maybe a week or 2. I was told at the time it is due to the residue or oils in the piping. So it should work its way out. Also it could be due to running rich. But if it just started with the new exhaust, I am def leaning towards it will go away....

It's my understanding that because the multiple computers on this car are very sensitive, whenever any performance mod is added a tune must be done in order for everything to work properly. You might want to head to the nearest performance shop and have them tune your computer for the new exhaust.

Probably both. The car runs rich on stock tune but more so the oils from production are burning off.
My Protege5 runs pig-rich at WOT - but you don't 'see' black smoke. I just have excess carbon on the intake manifold and EGR that i have to seafoam once every 30K miles...
