Pulsar XT is an all-new take on performance and calibration for your 3.0L EcoDiesel Jeep Wrangler JL or Gladiator JT and it's unlike any other device on the market. Pulsar XT is an innovative inline module engineered to keep your factory PCM untouched, leaving no trace in the system when removed for dealer service. Add up to 38hp/73ft-lbs torque to your Jeep diesel 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 and user adjustable throttle pedal sensitivity. Pulsar XT also offers full calibration adjustment through an innovative smartphone app that allows you to adjust your speedometer for larger tires and gear ratio changes, manual engine fan control and more. The intuitive mobile app gives you control over TPMS settings, can disable your Auto Start/Stop, modify engine high idle settings, and even do a manual DPF Regen cycle if needed. Giving Jeep owners even more control, Pulsar XT has the ability to enable your rear locker in 2wd for more fun in the sand or snow, front + rear lockers in 4wd High, and even disconnect your Rubicon's sway bar up to 45mph in any t-case mode. Frustrated your factory Traction Control still limits your off-road ability? Pulsar XT will completely kill that Traction Control system, electronic stability and disable ABS for the ultimate off-road experience at the push of a button in the app. Pulsar XT will also allow you to check and clear DTC's, check emissions readiness, reconfigure your lighting options, and calibrate for transfer case ratio changes. 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 diesel engines over 20-years and Pulsar XT is the most advanced 3.0L EcoDiesel device 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 diesel Jeep reacts with Pulsar XT, we can guarantee it. Our 2022 Gladiator on 35's shaved 1.38-seconds off it's 0-60mph times and picked up 3.5mph in the 1/4-mile with XT on Level 5! It's power and torque you'll feel from the seat.
