Description
Overview
The DiabloSport inTune i3 + Unlocked PCM Kit is a purpose-built computer chip programmer for the 2021 Dodge Challenger equipped with the 5.7L or 6.4L HEMI. For HEMI owners who want power you can feel, sharper drivability, and real tuning flexibility, this DiabloSport programmer delivers factory-friendly performance gains with the added freedom of a fully unlocked PCM. It’s engineered to unlock the potential already sitting under your hood and give you control over how your Challenger runs.
Everything is managed through a bright color touch screen display, so loading tunes, adjusting settings, and reading data is quick and intuitive. Because this is a gasoline application built specifically around the 2021 Challenger platform, you get calibrations and support matched to the 5.7 and 6.4 HEMI engines rather than a generic, one-size-fits-all handheld.
Key Benefits
Preloaded performance tunes let you extract more from your HEMI, while the unlocked PCM opens the door to deeper customization. If you want to go beyond the shelf files, the inTune i3 accepts custom tunes from CMR, giving enthusiasts and professional tuners a path to dial in a setup that fits their exact goals and modifications. Wi-Fi updates keep the device current without extra hardware, and built-in data logging with 5-volt data logging inputs lets you capture and review real-world performance data as you tune and troubleshoot.

Options & Media Explained
This kit pairs the inTune i3 handheld tuner with an unlocked PCM, combining an easy-to-use, screen-driven interface with the hardware freedom needed for advanced tuning. Note that the device is not video capable, does not include an AC adapter, and does not offer in-cab monitoring, so it’s focused squarely on tuning, data logging, and calibration control rather than dash-style gauge display.
Fitment & Compliance
