A DiabloSport Modified PCM allows you to unlock the performance potential of your 2021 JL with the 2.0T engine. This Performance Kit includes a DiabloSport Modified PCM for your vehicle as well as an inTune i3 handheld programmer.Jeep has made the 2.0T Hurricane motor the go-to engine in most Wranglers they build these days. While it may not offer the same performance as the 3.6 Pentastar in stock form, a simple tune can swing the favor toward the 2.0T. By optimizing the calibration and taking advantage of the flow offered by the factory turbocharger, we are able to provide gains of 22 horsepower at the rear wheels when running 93-octane fuel. Of course, we offer tunes for 87 and 91 octane as well, with comparable gains. In addition to more power, we offer useful functions like speedometer calibration for larger tires, idle speed adjustments, and much more.As with all newer Jeep applications, an unlocked PCM and bypass module are required for tuning. Our PCM swap and PCM + Tuner (pkit) options both include the bypass module as well as either a pcm swap or new unlocked pcm to use in your vehicle. These options eliminate downtime and allow for easy installation in your driveway.TUNES AND REAR WHEEL HORSEPOWER LEVELS:Diablo Tune (93 Octane) - 22 HP & 21 LB-FT of TQ91 Octane Tune - 20 HP & 19 LB-FT of TQ87 Octane Tune - 12 HP & 14 LB-FT of TQCrawl - (87 Octane) - 12 HP & 14 LB-FT of TQMPG Booster
