Do you need an Actuator?
If you're wondering whether or not you should buy an actuator to go along your new Stealth Turbo, here's what you should know. The 2017-2023 6.6L Duramax turbo actuator has a very low failure rate in the field. The fact that it's well-cooled and not with-in close proximity to any hot parts like the turbo means that it's out of harm's way. Unless you're experiencing codes that indicate actuator issues or know for a fact that your actuator is somehow damaged, we would suggest saving your money and retaining your factory actuator.
