Message with them switched to OEM and operation cleared up. I believe the aftermarket PCVs are not calibrated to OEM specs - probably different spring rate. Also the OEM hoses have a restrictor orifice inside the hose.

inf lists car as a 2000 TT so not sure of the PCVs and hoses in that model year.
