Product Details

The DiabloSport inTune i3 is a third-generation, handheld performance programmer that puts professional-grade vehicle calibration directly in your hands — no laptop, no shop visit, and no additional tools required. Simply plug into the OBD-II port and unlock real, measurable gains in horsepower, torque, and throttle response backed by extensive dyno and street development. The inTune i3 product line spans a broad range of Ford, GM, Dodge, Ram, Jeep, and Chrysler applications, with standard and Platinum variants available to suit everything from everyday drivers to heavily modified builds.

Key Features:

  • Dyno-Tested Performance Tunes: Pre-loaded calibrations developed and validated on the dyno and street, targeting meaningful improvements in horsepower, torque, and overall drivability
  • High-Definition Touchscreen Interface: Responsive HD touchscreen powered by an ARM processor for fast read/write operations and intuitive, menu-driven navigation
  • Easy Tune Mode: Guided setup walks users through octane selection, tire size, speed limiter preferences, and performance goals for a quick and straightforward tuning experience
  • OBD-II Diagnostics: Reads and clears diagnostic trouble codes (DTCs), monitors real-time engine parameters, and supports data export to DiabloSport's Data Viewer software for in-depth analysis
  • Transmission Tuning: Adjust shift points, shift firmness, rev limiters, speed limiters, tire size calibration, and gear ratios directly from the device
  • Wi-Fi Updateable: Wirelessly update firmware and tune files; compatible with Windows, Mac, and Linux operating systems
  • Multi-Vehicle Licensing: Optional additional vehicle licenses allow a single inTune i3 to support tuning across multiple compatible vehicles
  • Return to Stock: Automatically saves the factory calibration, enabling quick and complete restoration to OEM settings at any time
  • 50-State Legal Options Available: Select variants carry CARB Executive Order (E.O.) certification for emissions compliance in all 50 states
  • Platinum Custom Tuning Support: Platinum variants are compatible with CMR (ChipMaster Revolution) custom tune files, enabling professional tuners to load bespoke calibrations for modified or heavily built vehicles

More Than Just a Power Adder:

The inTune i3 recalibrates core engine parameters — including fuel delivery, ignition timing, idle behavior, and transmission shift characteristics — to recover performance that factory tunes intentionally leave on the table. Whether the goal is improved towing capability, sharper acceleration, enhanced throttle response, or better fuel economy potential, the inTune i3 product line offers tuning profiles tailored to a wide range of driving styles and use cases.

About DiabloSport:

An industry leader in vehicle calibration since 2001, DiabloSport has built its reputation through relentless innovation and a commitment to maximizing performance from late-model domestic vehicles. As part of the Holley Performance family of brands, DiabloSport continues to develop accessible, professional-grade tuning tools that put real control in the hands of enthusiasts and professional calibrators alike.

VERY EASY

As soon as I went to install the part a cheap screw that was supposed to hold it in stripped instantly so I had to go to the hardware store to find a replacement

Great experience. Super fast from order placement to delivery.

Perfect

.

Delivery was a little slow, but that could have been caused by the big storm

Hopefully this ships as fast stated
