Swapping Your Actuator:

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.

Is this the right turbo for you?

• YES! If you want peak power potential without having to build your engine.
• YES! Assuming you need a drop-in replacement turbo with upgrades to prevent the failures your stock turbo had. 
• YES! Only if reliability and performance make the top of your priority list.
• YES! Especially if you tow with your truck. 
• YES! Supposing that you want to make more power when you need it but still have excellent street manners.
• YES! 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  DuramaxTuner's custom EFILive 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.  Furthermore, 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
