The factory MAP (Manifold Absolute Pressure) sensor on the 2016-2021 LWN 2.8L Duramax is only capable of reading up to 29 psi gauge pressure. 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 drive-ability, you need an upgraded MAP sensor. Fortunately, DuramaxTuner has your back with their Stealth MAP Sensor specifically calibrated for your truck and those running the Stealth DT44 Turbo. This more accurate MAP sensor provides the ECM with precise data about the engine's intake manifold pressure, enabling the engine to adjust fuel injection, ignition timing, and boost levels more effectively. This can result in smoother acceleration, increased horsepower, and better overall performance. The sensor can also aid in better control of the turbocharger's operation. The ECM can adjust the turbo boost levels based on accurate pressure readings, reducing turbo lag and optimizing power delivery. Vehicle Fitment: 2016, 2017, 2018, 2019, 2020, 2021 2.8L Duramax LWN
