Yeah, two years ago LOL but I see you periodically post and I didn't want to start a new thread. I was researching areas to tap into for the BOV. I also have radium dual catch can kit.

Yea I recommend you use that PCV top port in the manifold if your catch can vents to atmosphere

The brake booster on the autos is getting vacuum from a vacuum pump attached to the back of the head on the passenger side. It gets no reference from the intake manifold which is where you would measure boost from. The manual cars attach to the back of the manifold so teeing off of the brake booster on manual cars will give you the proper reference.
