This device allows manual adjustment of boost pressure to a set value, increasing your vehicle's power output.

New model features:

• Larger diameter ceramic ball for increased reliability
• Two springs for a wider adjustment range
• 6mm fittings

Operation: Set the desired boost pressure (e.g., 0.5 bar). The valve remains fully closed until the preset pressure is reached in the system. Once the critical value is exceeded, the valve opens completely, resulting in rapid boost buildup. This provides full boost from the outset, even with the throttle partially open.

When using a manual boost controller (MBC), it is recommended to install a boost pressure gauge for monitoring. Pressure-type valves are connected in the pressure line to the wastegate actuator and feature a vent channel to the atmosphere.
