Mini Maxx V1 Diesel Tuner – Maximum Control. Maximum Power.
Take full control of your diesel truck with the Mini Maxx V1, a powerful all-in-one tuner designed for drivers who want serious performance, real-time monitoring, and total customization. Featuring a sharp, full-color display and fast, intuitive controls, the Mini Maxx V1 lets you adjust settings, monitor vital data, and switch tunes with ease.
Built for Cummins, Powerstroke, and Duramax platforms, the Mini Maxx V1 supports complete DPF, DEF, and EGR system disablement for off-road and race-use applications. It also eliminates related diagnostic trouble codes and check engine lights while protecting your engine with built-in safety protocols that monitor EGT, boost pressure, transmission temperature, and coolant temperature.
Depending on application, the Mini Maxx V1 can unlock up to 300 horsepower, transforming your truck’s throttle response, torque delivery, and overall drivability. With over 20 live digital gauges, speedometer recalibration for larger tires or gear changes, and customizable features like high idle and lighting controls, this tuner is as functional as it is powerful.
Everything arrives ready to install with all hardware included and tune files preloaded—no extra purchases required.
