Keep the pressure on
An AVO actuator endows the factory turbo with a more solid boost response while ensuring boost is maintained at a preset level, resulting in increased torque and hp. Where the factory actuator drops 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.
