GFB 2008+ Mitsubishi Lancer Ralliart (4B11T) WGA Wastegate Actuator (Tune Required)

The Go Fast Bits WGA Wastegate Actuator Tune 7300 is a high-performance internal wastegate actuator designed to improve boost control. It features an industry-first diaphragm design with a bead retention system for a larger effective area and smaller diameter, providing more control authority over the wastegate flap. The actuator offers an 18mm longest stroke, suitable for large internal wastegates or increasing boost pressure. Its pivoting rod guide is machined from PEEK for low friction and superior wear resistance, and the overall design minimizes bulk, making it the shortest actuator on the market.
