Startup black smoke causes?

[DarkMesa8]

What are the general causes of the rich puff of black smoke on startups?

It happens pretty regularly, and its nothing massive.

Motor is blown with a V2-SQ, 39lb injectors, lightning MAF, and SCT tune.

I'm starting to trouble shoot it.

you may be tuned to run rich at low RPM and start up to avoid tip in detonation

Are the fuel maps for startup and low RPMs the same, or are they different charts?
