The GFB EVO Internal Wastegate Actuator (IWG) provides better turbo response and greater sensitivity when managing boost pressure levels.
Comes with 3 springs which can be used individually or installed together to achieve different boost levels. The 7psi and 10psi springs are pre-installed for a gate pressure of 17psi, which is suitable for most EVO applictaions.
Gate pressures that can be achieved, 5,7,10,12,15,17, and 22psi.
Spring selection guide and assembly/insstallion diagram included.
Note: It is always recommended to have your car tuned after installations as it will result in higher boost pressure which the standard ecu program is not tuned for.
