By using a significantly larger diaphragm area than the OEM actuator, the WGA has more control authority over the wastegate flap, meaning exhaust backpressure cannot override the flap position as easily, resulting in more stable and reliable boost control.\u003c\/p\u003e\n\u003cp\u003eSupplied with 3 springs and a unique turnbuckle pre-load adjustment, the base boost pressure can be configured and adjusted from 5psi to 24psi for the best possible boost control.\u003c\/p\u003e\n\u003cp\u003eRead on for more technical information on wastegate springs, and how the correct spring selection can improve performance.\u003c\/p\u003e\n\u003cp\u003eThe WGA features a longer stroke, shorter height, and more adjustment than its rivals.\u003c\/p\u003e\n\u003cp\u003eWGA part # 7304 is designed to bolt on to Subaru WRX models from MY97-07 with the factory TD04 turbo.
