Description
Overview
The DiabloSport inTune i3 is a handheld computer chip programmer built specifically for GM gasoline vehicles from Buick, Cadillac, Chevrolet, GMC and beyond. This all-in-one tuner delivers dyno-tested performance tunes that instantly wake up your engine—boosting horsepower, torque, throttle response, and everyday drivability—without ever opening the hood. Just plug it in, follow the on-screen prompts, and let the i3 do the heavy lifting.
Where many programmers force you to choose between real power and legal compliance, the inTune i3 refuses to compromise. It is 50-state legal and CARB (California) compliant under C.A.R.B. E.O. #D-770, so you can run stronger tunes with confidence no matter where you drive.
Key Benefits
At the heart of the i3 is a bright color touch screen display that makes tuning simple and intuitive. Navigate performance tunes, review data, and dial in your setup with easy taps instead of confusing button combos. Built-in Wi-Fi updates keep the device current, pulling down the latest software directly so your programmer stays fresh over time.
Beyond raw power, the i3 doubles as a smart in-vehicle tool. Onboard data logging lets you monitor and record vehicle parameters, while dedicated 5-volt data logging inputs expand what you can track. It also handles speedometer correction, an essential feature after tire or gearing changes, keeping your readings accurate.
