Stick with the factory or the Forge recirc. There are people running 25psi w/ the stock valve functioning fine including AlfriedSq among others. The BOV will just cause your car to not function the way it was meant to b/c of MAF confusion. I have removed the intake silencer and you can now hear the factory valve and the turbo much easier, MUCH EASIER. It's almost too much. SO just stick with that mod, then you're not confusing the ECU and your car will run the way it's supposed to.
