Collection: Cummins Tuner Delete Kit

1. Why Should You Install a Delete Kit on Your 6.7 Cummins?

If you drive a Dodge Ram 2500 or 3500 with a 6.7L Cummins engine, you’ve probably noticed that emissions systems can hold back your truck’s true performance. Whether you’re towing heavy loads, daily driving, or just looking for better throttle response and fuel economy, installing a delete kit for 6.7 Cummins can make a dramatic difference.

1.1 What Is a Delete Kit?

A delete kit is a custom solution designed to remove factory emissions systems like the EGR (Exhaust Gas Recirculation), DPF (Diesel Particulate Filter), and DEF (Diesel Exhaust Fluid) components. When paired with a compatible tuner, a 6.7 Cummins tuner delete setup can unlock your engine’s full potential.

1.2 What Can You Expect?

• Lower exhaust temps—ideal for heavy-duty or high-performance applications

• Increased fuel efficiency—saving money with every mile

• Improved torque and throttle response—enjoy a more powerful ride

• No more forced DPF regens or DEF refills

• Lower maintenance costs and extended engine/exhaust system life

Choosing the right 6.7 Cummins delete tuner is key to achieving these results. SPELAB’s kits offer complete packages with reliable components and trusted tuning support, giving you the perfect balance of power, safety, and durability.

6. FAQ – Common Questions Answered

When considering a 6.7 Cummins tuner delete kit, many truck owners have similar questions. Below, we’ve answered some of the most frequently asked ones to help guide your decision-making process.

❓ Will deleting my 6.7 Cummins void the warranty?

Yes. Performing a delete tune for 6.7 Cummins—removing the DPF, EGR, or DEF systems—can void your factory powertrain warranty. If your truck is still under warranty, consider the risks carefully or consult with a trusted diesel shop.

❓ Can I daily drive a deleted truck?

Absolutely. Thousands of drivers daily their deleted trucks without issue. With proper tuning and regular maintenance, a tuner for deleted 6.7 Cummins can offer smoother performance, better throttle response, and even improved MPG.

❓ Will a delete kit improve my fuel economy?

Yes. Most users report a 10–15% increase in MPG after installing a DEF delete kit for 6.7 Cummins, especially when combined with a tuner and full DPF delete pipe. Real-world results may vary based on driving habits and tune selection.

❓ Do I need custom tuning, or is the preloaded tuner enough?

SPELAB delete kits include preloaded tunes via the Mini Maxx V1 or V2, so no custom tuning is required for most builds. These tunes are tested and reliable, covering all major emissions deletes (DPF, EGR, DEF). For advanced builds (larger turbo, injectors, etc.), custom tuning may be beneficial.

❓ What’s the difference between DPF delete and full delete?

• DPF delete removes only the diesel particulate filter.

• Full delete typically includes EGR, DPF, DEF, and CCV deletes, providing maximum airflow and performance.
  If you're looking for a complete 2018 6.7 Cummins delete kit with tuner, we recommend choosing a full delete setup for best results.

❓ Will I get a check engine light (CEL) after installing a delete kit?

No, as long as the tune is installed before removing emissions parts. The tuner disables the related sensors, preventing codes. Both Mini Maxx V1 and V2 are designed to work seamlessly with our kits.

❓ Can I pass inspection with a deleted truck?

In most areas, deleted trucks are not legal for on-road emissions compliance, especially in states with strict testing (e.g., California). These kits are intended for off-road or race use only. Always check your local laws before deleting.

If you have any other questions about your specific setup—whether you're running a 2016 Ram 2500 delete kit with tuner, or a 2008 6.7 Cummins DPF and EGR delete kit with tuner—our team is here to help.
