1990 N/A GTU AirCcontrolValve
I recently installed a full RB true dual exhaust system on my car. I realize the airpump must be retained for proper 5th/6th port operation.
However, must I retain the Air control valve? I have the Block off plate from racing beat and curious if this must remain on the vehicle.
Thanks,

yes, on an S5 NA the air pump air is used to open the 5th/6th ports and VDI
