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 2017-2023 Duramax 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.  
 
Important Notice:
This turbo uses a customized nozzle ring and/or shroud plate.  It’s been engineered to provide amazing response and performance. 
This turbo must only be operated with tuning that uses stock Minimum and Maximum Vane Position tables. Failure to do so can lead to excessive exhaust pressure and boost which may shorten the life of the turbo or engine and may void the turbo warranty.
Damage caused as a result of non-stock vane position tuning modifications will be the responsibility of the owner, not Calibrated Power Solutions Inc. If you have any questions or concerns please contact CPS at 815-568-7920.
Warranty: All Stealth Series turbos offer our Unlimited Mile, 1-year manufacturer warranty for quality and craftsmanship. For warranty inquiries please contact sales@duramaxtuner.com
