DiabloSport PKITJT3620-I3 Computer Tuner/Programmer for 2020 Jeep Gladiator 3.6

The DiabloSport inTune i3 Platinum + Unlocked PCM Kit is the ultimate tuning package for the 2020 Jeep Gladiator 3.6L Pentastar. From the factory, these trucks are equipped with locked PCMs that block tuning, but this kit provides everything you need to safely unlock your Gladiator’s full performance potential.\nThe inTune i3 Platinum handheld programmer (PN 8345) comes preloaded with dyno-tested performance calibrations designed for Jeep applications. Paired with the included DiabloSport Modified PCM and required gateway module, you’ll experience 15–20 rear-wheel horsepower gains, stronger torque, quicker throttle response, and improved 8-speed transmission behavior for smoother, more confident shifting.\nThese improvements translate to more power and better drivability both on the highway and off the beaten path, giving your Gladiator the responsiveness and strength it needs for towing, trail runs, or everyday driving.\nFor those adding bolt-ons or performance upgrades, the Platinum i3 supports CMR custom tuning, with access to DiabloSport’s nationwide network of tuners who can create dyno-proven calibrations tailored to your setup. Built-in data logging and diagnostics let you monitor and refine performance as your Jeep evolves.\n⚠️ Note for 2020 Models: You must save your stock calibration with your tuner before removing the factory PCM. Instructions are included for a smooth install.\nFor Gladiator 3.6L owners who want real horsepower gains, sharper throttle response, and better on/off-road drivability, the DiabloSport inTune i3 Platinum + Unlocked PCM Kit is the ultimate performance upgrade.
