Breather experts come in

So did the catch can setup for the ProCharge have it's own catch dedicated can on the driver's side for the "fresh air" side of the PCV system?

Of course going with breathers on both sides of the engine will totally eliminate oil from getting into the intake manifold, but as mentioned many times by TooSoonJunior there are negative issues with not evacuating the crankcase of nasty blow-by vapors.

Here's maybe a better way to go for forced induction:
I haven't seen anyone mention running a catch can on the passenger side ("dirty side" of the system) that's connected to the intake manifold as normal, and then run an open breather on just the passenger side ("fresh air side" of the system) to still allow the engine to draw fresh air through the crankcase under normal driving conditions.

With a setup that that, when the throttle goes WOT then the open breather can release excess crankcase pressure from boost blow-by without contaminating the intake manifold.

I assume you meant open filter on the DRIVER side. That is actually a common setup, but same as mentioned earlier that filter is gonna be oil soaked very quickly, as you still have oil coming out after a WOT pull. You will find a mist of oil all over the engine bay after a few months. Best to just put a puke can on it instead.

Because that would be a big vacuum leak. You could do it with the breathers that have the check ball in them though.

NO!!!! its open to air (filter or puke can) or routed to intake tube. Check valves would cause you to have vacuum in the crankcase since it cant suck fresh air in, the result will be pulling oil paste the rings and make blowby worse.

Correct. I was imagining it wrong.

I drank 1 too many monsters today lol. I always use a check valve breather on the oil cap. Peace of mind for me.

Marvinmadman was close though, as that setup (catch can on passenger side, and open breather on driver's side) would give "un-metered air" to the intake manifold.

On a stock PCV system, all the fresh air is routed through the engine after it's gone past the MAF sensor, so it's accounted for to accurately control the A/F ratio. If the driver's side was just an open breather, all the air sucked into the intake manifold from the passenger side valve cover would be un-metered air, and that would make the A/F ration a little leaner than it should be. So it's kind of like having a "vacuum leak".

Yep

Quick update: gutted the passenger side pcv. It seems to have resolved roughly 99% of my issue.
