Overview
Unlock the true potential of your late-model GM truck with the DiabloSport inTune i3 8225-R Computer Chip Programmer. Built for Chevrolet and GMC gas trucks equipped with the 5.3L and 6.2L engines, this complete tuning package finally delivers a solution for the 2019–2022 GM gas platforms that have long been locked down from the factory. If you’ve been waiting for a way to access real tuning capability on your late-model truck, the wait is over.
This kit centers around the industry-leading inTune i3 handheld tuner and pairs it with the specialized locksmith device and harnesses required to unlock both the ECM and TCM. That means full access to engine and transmission tuning, so you can move beyond factory restrictions and take command of how your gas truck performs and drives.
Key Benefits
The inTune i3 is engineered as an all-in-one tuning tool. A vivid color touch screen display makes navigating menus, loading tunes, and monitoring your truck intuitive and fast. Performance tunes are built in, giving you access to power-focused calibrations, while custom tuning support lets you dial in a setup tailored to your goals. The i3 also accepts custom tunes from CMR, opening the door to professional, application-specific calibrations.
Beyond tuning, the i3 doubles as a capable monitoring and diagnostic companion. Onboard data logging and 5-volt data logging inputs let you capture and analyze real-world performance data, while the built-in speedometer function helps keep your readings accurate. Wi-Fi updates keep the device current with the latest software without extra hassle.
