Why the Diablosport inTune i3 Platinum Is the Choice for Modified Vehicles
Preloaded tunes are developed for stock vehicles. They optimize the factory calibration for better performance across a predictable range of conditions and hardware. For most stock or mildly modified vehicles, the preloaded tunes in the standard inTune i3 deliver real, satisfying gains that transform the driving experience.
When the vehicle has been modified with a cold air intake, performance exhaust, camshaft upgrade, heads, or any combination of power adders, the preloaded tunes are no longer optimized for the actual state of the engine. A custom tune developed specifically for the vehicle’s modifications unlocks the full potential of those parts rather than leaving gains on the table.
The Diablosport inTune i3 Platinum enables custom tuning by adding support for tune files developed by calibrators in Diablosport’s CMR (Custom Motorsports Racing) network. These are professional tuners who work on the dyno with a customer’s specific vehicle, modifications, and goals to build a calibration that maximizes every parameter for that exact setup. The tune file is delivered to the customer digitally and loaded onto the Platinum device, which then flashes it to the vehicle’s PCM.
All of the standard inTune i3 features are included in the Platinum version: the ARM processor, high-resolution touchscreen, pre-loaded tunes, OBD2 diagnostic capability, Wi-Fi updates, transmission tuning, speedometer calibration, and multi-vehicle licensing. The Platinum designation specifically refers to the added capacity to receive and apply custom tune files beyond what ships on the device.
Platform-specific Platinum part numbers are available for GM vehicles (PN 8245), Dodge and Chrysler vehicles (PN 8345), and Ford vehicles. Confirm the correct part number for the target vehicle before ordering.
Who Should Choose the inTune i3 Platinum Over the Standard i3
- Owners with cold air intake, performance exhaust, or other bolt-on modifications
- Vehicles running custom camshaft profiles or cylinder head work
- Forced induction builds adding a supercharger or turbo kit
- Any owner planning to tune multiple stages of modifications over time
- Enthusiasts who want to work with a professional calibrator for maximum results
- Track and drag strip drivers who need a tune for specific racing conditions

Diablosport inTune i3 Platinum FAQ
The Platinum designation means the device is unlocked to receive and load custom tune files from professional calibrators. The standard inTune i3 only loads the preloaded tunes that come on the device from the factory. The Platinum version accepts tune files created by Diablosport’s CMR network tuners, allowing professional calibrations built for a specific modified vehicle to be loaded onto the device and flashed to the PCM.
Yes. The Platinum version includes all the same preloaded dyno-tested tunes as the standard i3 for the vehicle platform it is programmed for. The Platinum capability is additive: it adds custom tune file support on top of everything the standard device already does. Buyers who purchase a Platinum device can start immediately with the preloaded tunes and add a custom file later when they are ready to work with a professional calibrator.
A Diablosport CMR calibrator works with the vehicle owner to understand the specific modifications, goals, and operating conditions. The calibrator develops a custom tune file, often using data logs and dyno sessions, and delivers it as a digital file. The file is loaded onto the inTune i3 Platinum device using the device’s software. From there, the device flashes the custom calibration to the vehicle’s PCM the same way it applies any other tune. Multiple custom tune files can be stored on the device for different conditions or build stages.
For a completely stock vehicle with no planned modifications, the standard inTune i3 with preloaded tunes delivers the same power gains as the Platinum on a stock engine. The Platinum’s advantage is the custom tune capability, which only adds value when modifications exist or are planned. If there is any chance the vehicle will be modified in the future, buying the Platinum version upfront avoids the need to upgrade devices later.
