DiabloSport 8420 15-16 Jeep Wrangler 3.6 Computer Tuner/Programmer

The DiabloSport inTune i3 + Unlocked PCM Kit is the ultimate tuning solution for 2015–2017 Jeep Wrangler models equipped with the 3.6L Pentastar V6.

With this setup, you can gain up to 20 rear-wheel horsepower, improved torque, quicker throttle response, and refined transmission performance for smoother, more confident driving both on-road and off-road.\nFor Jeep enthusiasts who plan on adding bolt-ons or advanced modifications, the Platinum i3 supports CMR custom tuning, enabling dyno-proven calibrations tailored to your build. With built-in data logging and diagnostics, you’ll also be able to monitor and optimize performance as your Wrangler evolves.\nFor 2015–2017 Jeep Wrangler 3.6L owners looking for more power, better drivability, and reliable tuning flexibility, the inTune i3 + Unlocked PCM Kit is the perfect upgrade.
