IOBOX Performance Tuner for INEOS Grenadier by Agile Offroad

Bolt-On Driving Mode Control For The INEOS Grenadier

The IOBOX Performance Tuner gives your INEOS Grenadier enhanced throttle control with plug-and-play tuning modes for eco driving, off-road responsiveness, and aggressive power delivery. Includes Grenadier-specific mounting bracket for a clean, integrated install. 

Tailor your INEOS Grenadier’s throttle response with the IOBOX Performance Tuner, a plug-and-play module designed to provide dynamic driving control in any environment. Built with an intelligent, self-calibrating ECU interface, the IOBOX learns your vehicle’s throttle behavior on installation and adjusts each mode to deliver optimal performance. 

With selectable Eco, Sport, and Xtreme modes, you can soften pedal inputs for better fuel economy, sharpen response for highway driving, or go full aggression for off-road or performance use. The system is fully reversible, doesn’t require cutting or splicing, and includes a custom mounting bracket engineered specifically for the INEOS Grenadier dashboard layout.
