From the factory, these high-performance models are locked down against tuning—but this package provides everything you need to safely unleash your Hellcat’s true potential.\nThis kit includes a DiabloSport Modified PCM and the powerful inTune i3 Platinum handheld programmer (PN 8345). Preloaded with dyno-proven calibrations, the i3 Platinum delivers up to 30 rear-wheel horsepower gains, improved torque, sharper throttle response, and refined 8-speed transmission behavior for smoother, faster shifts. The result is a Charger that accelerates harder, responds quicker, and delivers a sharper driving experience both on the street and at the track.\nThe Platinum i3 also supports CMR custom tuning, connecting you with DiabloSport’s nationwide tuner network for dyno-proven calibrations tailored to your bolt-ons or advanced modifications. Built-in data logging and diagnostics make it easy to monitor and fine-tune your Hellcat’s performance as your build evolves.\n⚠️ Important Note: On 2021+ vehicles, you must save your stock calibration with your tuning device before removing the factory PCM. Instructions are included to guide you through a smooth install.\nFor 2021 Charger Hellcat owners who want serious horsepower gains, sharper drivability, and full tuning flexibility, the inTune i3 Platinum + Unlocked PCM Kit is the proven upgrade.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eFeatures and Benefits\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003e• 2021 Charger Hellcat 6.2\u003cbr\u003e• Performance TCM tune for 8 speed included\u003cbr\u003e• Up to 30 hp and 30 ft\/lbs torque on 93 octane\u003cbr\u003e• Tire Size Adjustment 20”-44”, allows for correcting speedometer for different tires\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• Raise or Lower Idle Speed by +\/- 400 RPM\u003cbr\u003e• Adjust Rev Limiter in Drive\/Neutral by +\/- 500 RPM\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• Disable Traction Control\/ESP\u003cbr\u003e• Required bypass cable is included\u003cbr\u003e• inTune 3 packed with preloaded tunes and end user adjustments\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":49023455527139,"sku":"PKITHCHAR21-I3","price":3448.8,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0660\/0821\/9875\/files\/13bb7b3076f0844c2d2879969b44ff20_9f244237-12a1-458c-b922-6eb75e20d90c.png?v=1779961085","url":"https:\/\/fastlanespares.co.nz\/products\/diablosport-pkithchar21-i3-intune-i3-with-modified-pcm-pkithchar21-i3","provider":"Fast Lane Spares","version":"1.0","type":"link"}
