Mini Maxx Tuner - V2 | DPF / DEF / EGR Delete Tuner

Mini Maxx V2 Delete Tuner – Complete Diesel Performance Upgrade

The Mini Maxx V2 Delete Tuner is a next-generation solution designed to deliver more power, improved fuel efficiency, and long-term reliability for Duramax, Powerstroke, and Cummins diesel trucks. Compatible with multiple years and models (see compatibility chart), it comes pre-loaded with delete tunes for DPF, EGR, and DEF removal, allowing your truck to run cleaner and stronger without triggering check engine lights.

With advanced tuning capabilities, the Mini Maxx V2 also supports top speed limiter adjustments, speedometer recalibration, and real-time monitoring of over 20 engine parameters. When paired with a DPF-delete exhaust and EGR block-off kit, drivers can see gains of up to 5 MPG and significant increases in horsepower, while also reducing combustion temperatures to help extend engine life.

Optional custom tunes are available for even greater performance, and the device is updateable via microSD or USB, ensuring your tuner stays current. Mini Maxx V2 is the all-in-one solution for removing factory emissions restrictions and transforming your diesel into a more powerful, efficient, and responsive machine.

The Mini Maxx V2 Delete Tuner is compatible with a wide range of Duramax, Powerstroke, and Cummins diesel trucks, covering both pickup and cab chassis configurations across multiple model years. Compatibility includes:

. (Sierra/Silverado 2500–5500) from 2007.5 to 2016, with Shift On The Fly (SOTF) available on earlier models.
. (F250–F550) from 2008 to 2010, and Powerstroke 6.7L from 2011 to 2019, with SOTF on select years.
. (RAM 2500–5500) from 2007.5 to 2021, with full SOTF functionality on most configurations.

Some important limitations apply: 2019–2021 RAM trucks currently support only one power level with a 20 PSI boost cap, though updated tunes are in development. LML Duramax models do not register boost levels until an upcoming firmware fix is released. Dual fuel tanks on cab & chassis configurations are not supported, and LGH trucks are incompatible. For RAM trucks from 2018–2021, a bypass cable is required for installation.

Please note that the Mini Maxx V2 will not support factory emissions systems. The stock pyro will not function with this tuner — to monitor exhaust gas temperatures, a BD Pyrometer Kit is recommended. Always verify compatibility before purchase to ensure optimal performance.

The Mini Maxx V2 Delete Tuner comes as a complete, ready-to-use package for diesel trucks, providing everything needed to unlock performance and remove emissions restrictions. The kit includes:

. Mini Maxx V2 Tuner
. OBD Connection Box
. HDMI Cable (for connecting the tuner to the box)
. Power Adapter
. MicroSD to USB Adapter
. Fuse Tap
. Tuner Mount
. USB Cable (for easy updates)
. Pre-loaded DPF, EGR, and DEF delete tunes

The Mini Maxx V2 Delete Tuner connects easily via the included OBD box, with HDMI and USB support for setup and updates. Some mechanical skill or professional assistance is recommended for optimal results. 2018–2021 RAM trucks require a bypass cable, and certain models may need minor modifications to exhaust or sensors. Pre-loaded tunes simplify installation, but professional tuning ensures maximum power, fuel efficiency, and engine longevity.
