For vehicles with EVC or other boost controllers, the upgraded actuator will solve "boost drop at high rpm" that is a week point of GDB.

 

 

◆Features

  •  Easy boost up with stock solenoid.
    Quicker boost increasing than stock actuator. As it can be used with stock ECU, it enables affordable upgrade from intake and exhaust tuning specification.  (*)
  • Using with EVC would solve the problem of boost drop at a high rpm.
    By using with EVC, it will prevent boost drop at high rpm by EVC rpm correction setting and improves peak power.
    With F-CON iS, stock turbine can produce ultimate boost up.
    "Boost spooling characteristic" can be adjusted by EVC. (Test was done with a restrained over shoot)

* This is in-house test result. You might need to set the ECU depend on the other installed parts or vehicle spec.
