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.\u003c\/p\u003e\u003cp\u003eIf you want to make more power than a 'tune-only' truck and you care about driveability, you need an upgraded MAP sensor. A STR truck can be tuned without an upgraded MAP sensor to make more power than a stock turbo. However, it's dangerous.\u003c\/p\u003e\u003cp\u003eYou 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.\u003c\/p\u003e\u003ch4\u003eYes, you need an Upgraded MAP Sensor\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWant to reach 280 HP\u003c\/li\u003e\n\u003cli\u003eCare about driveability\u003c\/li\u003e\n\u003cli\u003eRely on your truck as a daily driver\u003c\/li\u003e\n\u003cli\u003eNo, you probably won't need an Upgraded MAP Sensor: Stock Tuning\u003c\/li\u003e\n\u003cli\u003eNot interested in peak power.
