Pulsar XT is an all-new take on performance and calibration for your 2.7L/3.5L and it's unlike any other device on the market. Pulsar XT is an innovative inline module engineered to keep your factory PCM untouched, with no PCM swap or unlock required to add up to 65hp/90ft-lbs torque while improving drivability, throttle response and feature control. Enjoy Pulsar XT's shift-on-the-fly performance gains, with 5 power levels changeable through your factory steering wheel controls, with user adjustable throttle sensitivity in each power level as well. Pulsar XT also offers full calibration adjustment through an innovative smartphone app that allows you to adjust your speedometer for larger tires, transfer case ratio changes and gear ratio changes. The intuitive mobile app also gives you control over TPMS settings, can disable your Auto Start/Stop, lighting controls, read and clear DTC's and more. The device also offers cold engine protection so no power is added until you're up to operating temperatures, keeping your engine safe. We've been tuning Ecoboost engines since their inception and Pulsar XT is the most advanced plug in module on the market offering more features than the competition at a lower price. Don't settle for less, or spend your hard earned cash on two or three different devices that still won't give you everything Pulsar XT can. You'll love the way your truck reacts with Pulsar XT. *Does not currently support PowerBoost applications
