H&S Mini Maxx Delete Tuner for Your Diesel Engine

The Mini Maxx is the go-to choice for diesel owners who want straightforward, reliable tuning without the complexity. This handheld tuner removes emissions equipment limitations, letting your engine breathe and perform the way it should. No guessing, no corporate restrictions—just power.

2006-2012 Ram 6.7L Cummins

The 6.7L Cummins in your 2006-2012 Ram comes factory-hobbled with DPF and EGR systems that kill efficiency. The Mini Maxx V1 for Cummins deletes these restrictions, unlocking better fuel economy, cooler EGTs (exhaust gas temperatures), and real horsepower. This is the most popular choice for second-gen Cummins owners.

2003-2014 Ford Powerstroke 6.0L & 6.7L

Ford Powerstrokes—especially the problematic 6.0L (2003-2007)—are famous for DPF and SCR (selective catalytic reduction) headaches. The Mini Maxx V1 and V2.0 options for your Powerstroke eliminate these weak points. The 6.7L Powerstroke models (2011-2014) also benefit massively from delete tuning, getting cleaner internals and better reliability.

2007.5-2010 Chevy/GMC 6.6L Duramax LMM

The LMM Duramax is fully supported by the Mini Maxx V1. Delete the DPF and EGR to eliminate regen cycles and intake fouling on this generation.

2011-2016 Chevy/GMC 6.6L Duramax LML

The 6.6L Duramax LML came with strict emissions controls that tank performance. Our Mini Maxx V1 for Duramax removes the DPF and EGR burden, giving you the response and power this engine deserves.

Will a delete tuner void my truck's warranty?

Yes. Diesel delete tuning is considered a modification, and most manufacturers will deny warranty claims on emissions-related components or engine damage once they detect tuning. That's why this is only for off-road and competition use. Keep that in mind before purchasing.

Can I switch between tunes on the Mini Maxx?

Absolutely. The Mini Maxx stores multiple custom tunes and you can load them whenever you want. Some owners keep a mild tune for highway driving and a more aggressive tune for towing or off-road. It's flexible.

Does delete tuning damage my engine?

When done right—with a quality tuner, proper EGR cooler upgrade, and sensible driving—delete tuning actually improves engine health. You're running cooler EGTs, reducing carbon buildup, and cutting out the parts that fail most (DPF, EGR coolers). The engine sees less stress, not more.

Which is better: Mini Maxx V1 or V2.0?

The V1 is proven, reliable, and handles most applications without issue. The V2.0 is newer and has updated software features, but both work great. For most trucks, the V1 is the smarter buy since it's less expensive and the real-world difference is minimal.

Do I need a DPF delete kit hardware along with the tuner?

The tuner alone removes the software restrictions and warnings, but physically deleting the DPF and installing a downpipe is a separate job. Many owners do both for maximum flow and reliability. Check out our DPF delete hardware section for compatible kits.

How long does tuning take?

Loading a tune takes 5-10 minutes via the Mini Maxx's interface. You plug in, select your tune file, and let it flash. No dealer visit needed.

Is the Mini Maxx compatible with my truck?

We offer Mini Maxx tuners for 2003-2014 Powerstroke, 2006-2012 Cummins, and 2011-2014 Duramax. If your engine and year aren't listed in our collection, it's not compatible. Check the product pages for exact model coverage before ordering.
