Car running rich with tune?

Using bama 91 tune for my 05 gt for my cai and axleback for a few months now. Noticed that when I walked around the back of the car the other day the tips were covered in black residue. Decided to take my slps off and change the exhaust. When I pulled off the exhaust it was covered in the black stuff it was literally caked on. Noticed car smokes a little upon first start up. Took off throttle body but was completely clean. Problem with car or tune, opinions?

To turn things black it would have to be so rich it wouldn’t run right. Your probably sucking oil through the PCV valve.
