Description
Upgrade your turbo today! The L5P / L5D Stealth 64 is the most versatile drop-in turbo ever bolted to the 2020, 2021, 2022, or 2023 6.6L Duramax. While capable of providing enough airflow to support up to 700 RWHP this stock appearing unit still lights quick and is great for daily driving, towing, and putting Powerstrokes in their place.
This turbocharger features HFV technology! HFV or High Flow Vane technology is our proprietary customization of the variable vane cage and nozzle ring assembly. This advancement allows the use of a larger turbine wheel for maximum high-load efficiency. Stealth turbos featuring our HFV upgrade are capable of producing more power, spooling up quicker, and managing EGTs better than those limited with factory nozzle rings.
Your truck is going to experience increased performance across a wide operating range due to our HFV assembly, oversized turbine wheel, and billet compressor wheel. Built from brand new parts, this turbocharger won’t require a core charge. The optional actuator is pre-calibrated and the entire turbo comes ready for installation. YCustom tuning is required to run this turbocharger on your truck and specific min/max vane positions are required (check bottom of this page). Deletes are not required. We have made up to 650 RWHP when matching this turbo with our Custom Emissions Equipped Tuning.

THIS TURBO DOES NOT COME WITH A NEW ACTUATOR
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 2020-2023 6.67L Duramax turbo 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.
