Important
・It is important to note that when the boost controller is in the OFF mode, boost is only controlled by
the wastegate spring tension. It is common for vehicles that had factory boost control solenoids
removed, to have lower then factory base boost levels.
・Depending on the vehicle s wastegate or actuator spring tension, base boost levels many very.
・ A boost controller cannot lower the boost pressure below the wastegate and actuator s base
boost level.
・Turning OFF the Profec boost controller will not turn off the unit s backlighting or Real-time
