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 berelying 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
