[[Image:manualboostcontroller.jpg|thumb|220px|A simple manual boost controller. A small screw is located in the top of the aluminum body to adjust bleed rate. This model is placed in the engine bay,; however, the vacuum line could be extended to allow it to reach into the passenger compartment.]]

A bleed-type manual boost controller simple mechanical and [[pneumatics|pneumatic]] control to allow some pressure from the wastegate actuator to escape or bleed out to the [[atmosphere]] or back into the [[intake]] system. This can be as simple as a T-fitting on the boost control line near the actuator with a small bleeder screw. The screw can be turned out to varying degrees to allow air to bleed out of the system, relieving pressure on the wastegate actuator, thus increasing boost levels. These devices are popular due to their negligible cost compared to other devices that may offer the same power increase.
