DO YOU NEED AN ACTUATOR?
If you're wondering whether or not you should buy an actuator to compliment your Stealth turbo, allow us to share our thoughts. The L5P actuator has a very low failure rate in the field. The fact that it's well-cooled and not in close proximity to the hot parts of 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.
