For 6.7L Cummins Owners:Looking to improve towing power and disable EGR/DPF without triggering codes? The Mini Maxx V1 tuner gives you full control with shift-on-the-fly tuning and up to +175 HP in performance mode. For 5.9L Cummins Users (2003–2007):While this tuner is not directly compatible with the 5.9 platform, SPELAB recommends alternative tuners purpose-built for 5.9L setups.  For 6.4 & 6.7 Powerstroke Enthusiasts:Whether you're daily driving or racing, Mini Maxx V1 offers selectable tunes from mild to extreme. Options like “Hot Damn 300” deliver serious power gains with proper upgrades. For LML Duramax Trucks (2011–2014):Unlock +150 HP while managing your DEF and DPF systems. All tuning is preloaded and ready to go. FAQ Q1: Does the Mini Maxx V1 delete emissions systems (DPF/EGR)? A1: Yes, it offers emissions removal tuning (where legally permitted). However: Check local laws—some regions prohibit DPF/EGR deletion. Deleting emissions systems may void your warranty.  Q2:  How much horsepower (HP) can I gain with the Mini Maxx V1? A2: HP gains vary by engine and tuning level: Mild Tunes (Tow/Street): +50–120 HP (better fuel economy + towing). Performance Tunes: Up to +300 HP (e.g., 6.4L Powerstroke "Hot Damn 300" mode).

Follow on-screen prompts to load tunes. No laptop or advanced skills needed. Includes pre-loaded tunes; no custom tuning required.  Q4: Will the Mini Maxx V1 cause engine or transmission damage? A4: Not if used responsibly: Stock/Tow modes are safe for daily driving. Performance modes stress the engine/transmission—ensure your vehicle is mechanically sound.

Q6: Can the Mini Maxx V1 tuner be used on a 5.9 Cummins?A6: The Mini Maxx V1 tuner is primarily designed for 6.7L Cummins engines and newer. It is not officially supported for the 5.9L Cummins; you may need a different model or legacy tuner specifically built for pre-2007 Cummins platforms. Q7: Does the Mini Maxx V1 tuner work with the 6.6L LML Duramax?A7: Yes, the Mini Maxx V1 tuner is compatible with the 2011–2014 GM 6.6L LML Duramax.

Q9: Is this tuner street-legal for use on my 6.0 Powerstroke or 6.7 Powerstroke?A9: While the Mini Maxx V1 tuner can be used on 6.0L and 6.7L Powerstroke engines, emissions-related tuning may not be legal for on-road use in many areas. Always check your local emissions laws before installation or use of delete functions. ---tab Shipping & Returns--- Fast Shipping Policy Your order will be dispatched within 1-2 business days, and the package will arrive within your order's estimated date.
