you should be able to get rid of that regulator and tune into boost with the Mefi3. Fuel pressure remains constant and I bet your sooting issues disappear, unless you are seeing oil as Eddie mentioned before

I did notice this weekend that the valve cover vents to the intake of the blower. I might route that into a catch can and see if that helps.

that's a cheap vacuum pump and i doubt the cause of what you're seeing. if you're getting too much oil out of there you may have a blow-by problem
Let me ask you this...
does it soot on a run without going into boost? do you go into boost coming on plane?

Little to no soot not under boost. No boost getting onto plane.

one of the pros can chime in but I would bet the rate at which the regulator comes in under boost is very aggressive. That in itself may lead to the sooting problem since your afr seems to be good. I ran one from Bell Engineering and although it was a superior product compared to the one ProCharger supplies, it was very temperamental and a real pita to to keep tuned. Day to day weather changes would affect it so I went to mefi4 and did away with it altogether. I'd be interested in seeing your fuel map with the 80lb injectors.
