Mini Maxx Tuner V1 vs V2: Best Diesel Delete Tuner for 2026

The Mini Maxx is one of the most proven delete tuners on the market — preloaded, plug-and-play, and built for Ford Powerstroke, Dodge Cummins, and Chevy Duramax.

This guide breaks down both versions — V1 and V2 — so you know exactly which one fits your truck, your build, and your budget before you buy.

What is the Mini Maxx Tuner?

The Mini Maxx is a handheld diesel performance tuner by H&S Performance. It plugs into your OBD-II port and loads prebuilt delete tunes directly to your ECM.

It handles DPF, EGR, and DEF delete for off-road use — no laptop, no custom tune file, no remote tuner required. Just plug in and select your power level.

Compatible with Ford Powerstroke, Dodge Cummins, and GM Duramax. Available in two versions: V1 and V2.

Frequently Asked Questions

Which Mini Maxx should I buy for a 6.4 Powerstroke?▼
The V1 is the better pick for the 6.4 Powerstroke (2008–2010). It has more stable tune files for early-gen Powerstroke platforms and fewer known issues on that application. The V2 works but the V1 has a longer track record on the 6.4.
Does the Mini Maxx require a laptop or internet connection?▼
No. Both V1 and V2 come preloaded with delete tunes. Plug into the OBD-II port, select your tune, and flash. No laptop, no internet, no external software required. The V2 can receive wireless firmware updates when available.
Can I switch between power levels while driving?▼
Yes — both versions support Shift-On-The-Fly (SOTF). You can cycle between power levels without stopping. Add the SOTF switch for even easier on-the-fly control from a dash-mounted toggle.
Will the Mini Maxx clear check engine lights after a delete?▼
Yes. The delete tune reprograms the ECM to stop monitoring removed emissions components, which prevents those fault codes from triggering. The tuner also has a built-in DTC reader and clear function for any other codes that come up.
What trucks does the Mini Maxx support?▼
Both V1 and V2 support Ford Powerstroke (6.4L, 6.7L), Dodge Ram Cummins (5.9L, 6.7L), and GM Duramax (6.6L). The V2 has broader year coverage. Check the product page for your specific year and model before purchasing.
Is the Mini Maxx street legal?▼
The Mini Maxx and its delete tunes are intended for off-road use only. Use on public roads may violate federal and state emissions regulations. Check your local laws before purchasing.
