2.8L LWN Stealth DT 44 Turbo

Unleash the hidden power of your 2.8L Duramax with the Stealth DT 44 Turbo — engineered for maximum performance, reliability, and stealthy street manners. Designed as a direct-fit upgrade for the GM 2.8L LWN platform, the DT 44 delivers a perfect balance between fast spool, strong mid-range torque, and sustained top-end horsepower.

Built with premium materials and precision-balanced internals, the Stealth DT 44 Turbo provides a smooth, quiet operation while dramatically improving airflow and boost response. Its advanced compressor and turbine design ensure cooler EGTs, improved fuel efficiency, and enhanced towing capability — all without sacrificing daily drivability.

Whether you’re chasing peak performance, improved towing confidence, or simply a more refined driving experience, the LWN Stealth DT 44 Turbo transforms your 2.8L Duramax into a powerhouse that performs as good as it sounds.

The factory MAP sensor on the LWN 2.8L Duramax reads up to 29 psi (gauge) or 45psi (ambient).  A 2.8L running our custom tuning will command about 28 psi in the Daily 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 you need an upgraded MAP sensor.

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