Agency Power Manual Boost Controller. This manual boost controller is a bleed valve design, which has you connecting the hoses on either side to the compressor and the wastegate of the turbo. The valve controls the airflow through the valve by the adjusting knob. Loosen the knob and more air moves for higher boost pressure. Tighten the knob down and restrict the flow for less boost pressure.

This kit includes 2 feet of 5/32 vacuum tubing, a flexible aluminum bracket that bolts to the MBC and has predrilled holes for universal fitment, and hardware.
