PCV Delete, Catch Cans, and Unmetered Air

Catch cans between the valve cover and the intake pipes. I am boosted so my line of thinking was if I put it as stated then I would still have suction under boost. If I had put the catch cans on the intake manifold pcv tubes then I would have no suction under boost. I'm just hoping that the catch cans are efficient enough to prevent oil on getting into the intake. I haven't been able to install my set up because my car has been at Z1 waiting for a tune for a long time. Their dyno is broke.
