I was hoping you would chime in as you started a similar post. Not sure where to look? I know where the PCV is.... Its been this way well... since I got my first tune from Torrie.. stock doesn't have this problem..
Sorry man feeling a bit under the weather. 
I would also try to rule out your CAC(Intercooler) Z
Here's a simular link,hope it helps any.

I would add a bottle of Chevron fuel system cleaner or a few ounces of Marvel mystery oil to every tank to see if it helps any. I think you have a job 1 SHO IIRC which has a heated PCV and might be worth while to have it changed especially if original. Z

Good points! Haven't scoped the intake valves but I do know the plug gap is good. The O2 do get covered, but they seem to be functioning fine.
Engine oil probably needs to be sent off for analysis...
It is weird... stock programming and the soot issue is non existent. Throw a tune on it, and it's sooty...
I will say that the LMS tunes produce a significant amount less to almost no soot after the initial trims get set...
Just seems to be the SCT based tunes..

You have logged with the X4 with both the LME and the SCT tunes, right SBS? Nothing sticks out in the data? Are there some parameters that havent yet been logged that are now due? Is mpg better with the LME tune, since it seems to be burning cleaner?
I would say time to try an E blend, but that may only hide the issue rather than expose it.

I have logged both yes. The LMS tunes tend have better fuel trims... closer to 1 if you factor in LTFT's and STFT's so I do think that plays into it. Brad mentioned that SCT has really funky idling values for my strategy, he said he was surprised it idled at all.
I did run an E blended tune, and yes, that did make a difference.
Unfortunately I can't tell if I am getting much soot when driving around lol..
I did become much worse after the down pipes but that could have been the stock cats filtering out all the crap.
I follow a crazy over the top maintenance regimen with my plugs and fluids. Haven't touched the PCV gear at yet.. I will take a look at it...
The map sensors are generally pretty clean, they do get a very small amount of residue on them from the oil but that's not unusual. Not something you can see but you can feel it.
Maybe time to get the intake cleaned up? But I figured the meth would take care of that?
Dunno...
