It would act like a idle control valve , bypassing the throttle-body . only thing at low speeds, idle it suppose to work like stock, same vacuum .
On some of the vehicles the vacuum goes down lower at 2500 rpm so the valve is less restrictive than OEM PCV .
Thing is that would mess with map sensor as any extra flow would really be vacuum leak except it still gets metered if there is a MAF sensor used .

There is 1 review on there forum and in the end, longer time testing he got same mpg .

I don't like the fact the valve is closed for 2 min either, not good IMO ,if in fact it is totally closed .
