BOV Controller Kit - Kompact BOV - Black JRX9 Producing around 23 PSI ofThe Turbosmart BOV controller is an electronic device which controls the pressure signal to the BOV. It works by detecting a negative voltage change in throttle position. It then energises a solenoid to vent all of the air out of the BOV cap, causing a pressure differential between the piston of the BOV and the cap which will vent pressure from the intake system. Diesel engines can experience compressor surge when coming off the throttle. The
