Save on Fuel with the Diesel Tuner

The Mini Maxx is not only about performance but also about fuel efficiency. Many truck owners report significant gains in mpg, with some seeing up to a 5 mpg improvement when paired with the right DPF delete pipe and EGR block-off kit.

While H&S Performance tuners are well-known for their customizable options, many find the Mini Maxx V2 to be a more balanced and reliable option for daily use. Unlike other tuners that might require additional setup and fine-tuning, the Mini Maxx V2 comes ready to use with pre-loaded tunes for DPF, DEF, and EGR deletes. This means you can avoid the extra hassle and get on the road faster.

What Does the Mini Maxx Do?

The Mini Maxx V2 boosts your truck’s performance by increasing power, torque, and fuel efficiency. With it, you can delete several emissions systems, including:

• DPF (Diesel Particulate Filter): The Mini Maxx lets you remove all components of the DPF system while disabling the related sensors and eliminating any check engine lights.
• EGR (Exhaust Gas Recirculation): It disables the EGR function and turns off any related DTCs. Whether you leave the EGR installed or use an EGR block kit, the Mini Maxx has you covered. No more leaks from the EGR!
• DEF (Diesel Exhaust Fluid): This tuner shuts off the urea injection system entirely, so you can remove the DEF tank and sensors, reducing the overall weight of your truck.

With the Mini Maxx, ULSD (Ultra-Low Sulfur Diesel) becomes optional, allowing you to run high-sulfur diesel fuels if you prefer.

Before you install the Mini Maxx, please be aware that this diesel tuner is designed for off-road and race use only. Always make sure you’re in compliance with local emissions regulations.
