of course it is vta, wtf do I want to add extra flanges and hoses when building my i/c piping when I don’t need it, then buy an adapter to screw into the greddy rs so that I can dump warm air back into my intake. My car uses a gm mas that is behind the bov, the air that is dumped to atmosphere is never “counted” by my ecu.
So what do I have to gain from recirculation? unnecessary mods that don’t a hp = domestic status? mmmK
