I use my car differently than you, primarily a street car that I autocross. As you can imagine, autocross does a good job of stirring the oil on top of several RPM transients over the course of 40-50 seconds. Prior to running a catch can, I would get lots of oil residue in the intake manifold through the PCV. Eventually it got to the point where it was blowing smoke from so much oil going down it's throat! I tried not having the PCV connected to the vacuum port, but that made an oily mess everywhere. It sees like it made it own vent anywhere it could. That's when I added a catch can. I use a sealed can basically in series with the PCV and vacuum port. It's a rather small can and after about 6-8 autocross runs, it would be full. Under normal driving conditions, it would stay empty. I've always been curious how a vented tank will work on an NA car. I feel like they are more suited for boosted applications. I know you are boosted so likely a moot point.
