Show original supplier description
The H&S Mini Maxx V1 Tuner is a state-of-the-art diesel tuning solution for performance enthusiasts looking to overcome common issues like limp mode, costly DEF refills, and clogged filters. It boasts a high-resolution screen and responsive toggle controls for intuitive navigation, allowing for shift-on-the-fly tuning without needing to stop. This tuner supports full DPF, DEF, and EGR delete functionality, effectively removing check engine lights and deactivating urea injection systems. It is designed for Cummins, Powerstroke, and Duramax platforms, offering tailored engine tuning with potential HP boosts from 0 to 300HP. Key features include automatic safety backdown governed by EGT, Boost, Trans & Coolant Temp, over 20 live digital gauges for engine vitals monitoring, and the ability to adjust speed limiters and recalibrate speedometers for tire/gear changes. It also includes a built-in DTC reader and clearer, and allows for enabling/disabling features like high idle, fog lights, and chimes. The Mini Maxx V1 comes with preloaded street and off-road race tunes on an included Micro SD card, eliminating the need for external downloads. Installation is plug-and-play, requiring no physical EGR removal, though an EGR delete kit is highly recommended for long-term reliability. Updates are available via the SD card. It is important to note that this tuner and its delete capabilities are strictly for closed-course competition and off-road use only and are not street-legal, violating federal and state laws if used on public highways. Compatibility includes Dodge RAM (2500/3500) 5.9L & 6.7L Cummins (2006–2012), Ford (F-250/F-350) 6.0L, 6.4L & 6.7L Powerstroke (2003–2016), GMC/Chevrolet (2500/3500) 6.6L Duramax LMM (2007–2010), and GMC/Chevrolet (2500/3500) 6.6L Duramax LML (2011–2014). Specific exclusions apply: 2011-2016 Ford Cab & Chassis configurations are NOT supported, and the 2015-2016 Ford 6.7L may trigger a harmless crankcase ventilation sensor code. Additionally, 2003-2007 Ford and 2006-2007 RAM models do not have delete tunes.
