Its so rich that its blowing black smoke out the exhaust once it warms up (I think when it goes to closed loop) Is this normal or maybe the mechanic messed up the install?

What year are you? Do you have an intake with the EGR pipe?
Check that they put the o-ring back on the EGR pipe as it will suck in lots of air if there is no o-ring.
MY STFT were at about + 15 and my LTFT at +25 pumping in tons of gas due to the o-ring not being reinstalled.

When my O-ring wasn't in-place the car idled fine until it started to load up on fuel due to the high STFT and then start to bog.
There was no wide swing in rpms without the o-ring. I actually figured it out by listening for the vacuum leak.
