Factory PCMs are locked to prevent tuning, but this package includes a DiabloSport Modified PCM and the inTune i3 Platinum handheld programmer (PN 8345), giving you everything you need to safely unlock your SUV’s hidden performance.\nPreloaded with dyno-proven calibrations, the inTune i3 Platinum delivers 20–25 rear-wheel horsepower gains, improved torque, and sharper throttle response. Transmission calibrations enhance shift timing and smoothness, creating a more responsive, more refined driving experience. The kit also provides the option to disable MDS (Multi-Displacement System), keeping your Jeep in full V8 mode whenever you want maximum performance and sound.\nFor enthusiasts planning bolt-ons or future builds, the Platinum i3 supports CMR custom tuning, connecting you to DiabloSport’s nationwide tuner network for dyno-proven calibrations tailored to your modifications. Built-in data logging, diagnostics, and user-adjustable options give you full visibility and control over your Grand Cherokee’s performance.\n⚠️ Important Note: On 2019 models, you must save your stock calibration with your tuning device before removing the factory PCM. Detailed instructions are included.\nFor 2019 Grand Cherokee HEMI owners looking for real horsepower gains, MDS disable, and custom tuning flexibility, the inTune i3 Platinum + Unlocked PCM Kit is the ultimate upgrade.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eFeatures and Benefits\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003e• 2019 Grand Cherokee 5.7 and 6.4\u003cbr\u003e• Add 20-25 rwhp on premium fuel\u003cbr\u003e• Poerformance TCM tune included\u003cbr\u003e• Disable MDS\u003cbr\u003e• Supports custom tuning through our CMR tuner network\u003cbr\u003e• inTune 3 packed with preloaded tunes and end user adjustments\u003cbr\u003e• Speed      Limiter On\/Off enabling increased top speed\u003cbr\u003e• Target      Cooling Fan temps can be set from 150°-230° for use with cooler t-stat\u003cbr\u003e• Tire      Size Adjustment 20”-44”, allows for correcting speedometer for different      tires\u003cbr\u003e• WOT      Fuel Adjustment – 1-7K RPM +\/- 20%, allows for fine tuning Air\/Fuel Ratio\u003cbr\u003e• WOT      MBT Spark 1-7K RPM +\/- 10\u003cbr\u003e• WOT      Spark – 1-7k RPM +\/- 10\u003cbr\u003e• Full color touch screen device\u003cbr\u003e• WiFi update capability\u003cbr\u003e• Multi-license capability\u003cbr\u003e• Datalogs\u003cbr\u003e• Reads\/clears DTCs\u003cbr\u003e• Includes PCM Preprogrammed for your vehicle\u003cbr\u003e• Unlocked for use with DabloSport devices\u003cbr\u003e• OEM replacement\u003cbr\u003e• Removal\/Installation videos available on our YouTube channel\u003cbr\u003e\u003cbr\u003e\u003cem\u003e\u003c\/em\u003e","brand":"DiabloSport","offers":[{"title":"Default Title","offer_id":49023454478563,"sku":"PKIT-JGCV819-I3","price":3448.8,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0660\/0821\/9875\/files\/b069e10d75c66a33db317f8520e712ab.png?v=1779961049","url":"https:\/\/fastlanespares.co.nz\/products\/diablosport-pkit-jgcv819-i3-intune-i3-with-modified-pcm-pkit-jgcv819-i3","provider":"Fast Lane Spares","version":"1.0","type":"link"}
