Description
The GFB WGA is a premium internal wastegate actuator that provides much more precise boost control and greater stability than the standard actuator. Thanks to a larger membrane surface The wastegate can better resist exhaust backpressure, preventing the valve from opening too early. The result: more stable boost, faster response, and more reliable performance, especially with tuned engines.
The actuator offers both adjustable base boost (5–24 psi thanks to three included springs) as a turnbuckle preload adjustment for ultra-precise tuning. The compact, versatile design features a longer stroke and more adjustment range than comparable products. Specific to the EVO X, this WGA is direct bolt-on and comes pre-installed with 10 psi + 7 psi springs (17 psi base pressure).
