Frequently Asked Questions

Is the Mini Maxx V2 legal? ▼
The Mini Maxx V2 is designed for off-road and racing use only. Using it to delete emissions systems on road-legal vehicles violates EPA regulations and is illegal in all US states. Check your local regulations before use.
Will I get a check engine light after deletion? ▼
No. The Mini Maxx V2 tune completely disables all emissions fault codes and monitoring. When properly installed with the correct tune for your vehicle, you will not see any check engine lights related to DPF, EGR, or DEF systems.
Can I revert to stock tuning if I sell my truck? ▼
Yes. The Mini Maxx V2 can re-flash the ECU back to stock tune. However, you cannot physically remove the DPF, EGR delete components, or fill the DEF tank retroactively.
How often do I need to update the software? ▼
Updates are not required for normal operation. However, software updates are periodically released to add support for new vehicles, improve performance, or fix known issues. Updates are free and downloaded via SD card.
What's the difference between C&C and SOTF support? ▼
C&C (Cab & Chassis) trucks have a different electrical/ECU configuration than standard Super Duty Over The Frame (SOTF) trucks. The Mini Maxx has dedicated tunes for each variant.
Do I need a bypass cable? ▼
Only if you have a 2018-2021 RAM truck. These models have integrated security systems that require a bypass cable to access the OBD port for tuning. Most other trucks connect directly without additional cables.
Can Mini Maxx V2 remove the speed limiter? ▼
Yes. The Mini Maxx V2 can adjust or completely remove the factory speed limiter. This is done during the tuning process. You can select the desired top speed (or unlimited) when setting up your tune.
What does "real-time monitoring" mean? ▼
Real-time monitoring means you can view live engine data (boost, fuel pressure, temps, etc.) while driving. Connect the device to a laptop and you'll see 20+ parameters updating as you drive.
Is warranty void after tuning? ▼
Manufacturer warranty on emissions components will be affected. Most dealers will not warranty any emissions-related repairs on a deleted truck. However, your factory warranty on other components may still apply depending on dealer policy.
How do I know if Mini Maxx V2 is compatible with my truck? ▼
Check the compatibility table in this guide. It lists every supported vehicle by year and model. If your truck isn't listed, contact support to ask about future support or workarounds.

💡 Tip: The entire tuning process usually takes 15-30 minutes. Your truck will restart during the flash—this is normal. Don't turn off the ignition during this time.
