Description

The Stealth DT44 Turbo is an upgraded direct replacement for your 2016-2022 LWN 2.8L Colorado / Canyon (including ZR2 models). This turbocharger comes with a larger and stronger billet compressor wheel, a custom spec oversized turbine wheel, and Calibrated Power's exclusive HFV (High Flow Vane) technology. You'll have more peak power potential while maintaining optimal driveability. If you need a reliable upgrade for your failed stock turbo, or if you’re interested in better performance on a tuned truck, this is the perfect turbo upgrade for you. 

The 2016+ 2.8L Stealth DT44 Turbo is the most versatile turbo upgrade available for the LWN. It fits like a stock OEM turbocharger, but runs better in every way! The custom, oversized Stealth Nozzle Ring and oversized turbine wheel mean you can get on top of the turbo and make power quickly while the custom billet compressor wheel can supply 20% more airflow than stock.

Power Numbers:

  • Airflow to support 20% more power than custom tuning alone
    • 180 HP - LWN baseline
    • 230 HP - LWN with tune only
    • 280 HP - LWN with DT44 Stealth Turbo + Calibrated Power Solutions Custom Tuning + S&B Cold Air Intake + Modified MAP Sensor (+100 HP over Stock!)

Swapping Your Actuator:

The DT44 utilizes your factory actuator. This component is easy to access and can be swapped onto your new DT44 Turbo with simple tools and basic mechanical skills.

This the right turbo for you if:

  • You want peak power potential without having to build your engine.
  • You need a drop-in replacement turbo with upgrades to prevent the failures your stock turbo had.
  • Reliability and performance make the top of your priority list.
  • You tow with your truck.
  • You want to make more power when you need it but still have excellent street manners.
  • You like to upgrade what you can on your vehicles to get the best performance. 

Do You NEED an Upgraded MAP Sensor?

The factory MAP sensor on the LWN 2.8L Duramax reads up to 29 psi (gauge) or 45psi (ambient).  A 2.8L running Calibrated Power Solutions Custom EFI Live Tuning will command about 28 psi in the Sport Tune depending on altitude and temperature. That means your truck is at the limit of the MAP sensor with just tuning. If you want to make more power than a 'tune-only' truck and you care about driveability, you need an upgraded MAP sensor. 

A DT44 truck can be tuned without an upgraded MAP sensor to make more power than a stock turbo. However, it's dangerous. You will be relying on a custom tuner to safely set the min or max vane table in such a way as to keep the turbo safe.  You will see no more than the 29 psi of boost reported on electronic gauges.

  • Yes, you need an Upgraded MAP Sensor:
    • Want to reach 280 HP
    • Care about driveability
    • Rely on your truck as a daily driver
  • No, you probably won't need an Upgraded MAP Sensor:
    • Stock Tuning 
    • Not interested in peak power
