AVOTurboworld's 15PSI boost actuator for the factory turbo will give a more solid boost response while ensuring boost is maintained at a preset level, resulting in increased torque and hp. Where the factory boost actuator drops in boost as the revs rise, the AVO actuator delivers constant boost all the way to redline and beyond. An extremely safe, reliable and effective means of raising your boost level even when running a aftermarket wastegate solenoid. This will help the boost hit its target boost more quicker and reliably. Running the AVO 15PSI actuator on a automatic vehicle will help stop the boost creep in between gear changes.
