2018 Ram 2500 Delete Kit Guide: DPF, EGR & Tuning for the 6.7L Cummins

Why Delete a 2018 Ram 2500? (Common DPF & EGR Problems)

Owners of the 2018 Ram 2500 with the 6.7L Cummins often face issues with factory emissions systems:

• Frequent DPF Regens – Forces excess fuel burn, hurting MPG.
• EGR Clogging & Failures – Causes carbon buildup and reduced airflow.
• DEF System Malfunctions – Leads to limp mode and costly repairs.

A Ram 2500 delete kit eliminates these problems, offering:

• Better throttle response (less turbo lag)
• Improved fuel economy (3–5+ MPG gains)
• Reduced engine heat & longer turbo life
• No more forced regens or DEF headaches

Types of Delete Kits: DPF-Only vs. Full EGR/DPF/DEF Deletes

1. DPF Delete Pipe (Catalyst & Soot Filter Removal)

Removes the restrictive Diesel Particulate Filter for better exhaust flow.

Requires a tuner to disable regens and prevent check engine lights.

2. EGR Delete Kit (Cooler & Valve Removal)

Stops soot recirculation, keeping the intake cleaner.

Includes block-off plates to seal the system.

Recommended EGR Delete Kit

3. Full Delete Kit (DPF + EGR + DEF Removal)

Best for maximum performance (off-road use only).

Requires a custom tune to avoid engine codes.

Tuner Requirements: Why Tuning is Critical After a Delete

⚠️ Warning: A delete without tuning will trigger check engine lights and limp mode.

Best Tuners for a Deleted 6.7L Cummins:

• EFI Live (most customizable)
• H&S Mini Maxx (user-friendly)
• MM3 by EZ Lynk (wireless tuning)

🔧 Pro Tip: Always choose a reputable tuner to prevent engine damage.

Installation Tips: DIY vs. Professional Pros/Cons

DIY Installation (Moderate Difficulty)

• Pros: Saves money, full control over the process.
• Cons: Requires mechanical skill; mistakes can cause leaks.

Professional Installation

• Pros: Guaranteed fitment, no risk of errors.
• Cons: Higher cost ($500–1,000+ depending on shop).

📌 For most owners, a DPF/EGR delete is DIY-friendly, but a full delete may need a pro.

Legal & Warranty Considerations

🚨 Important: Deleting emissions systems is illegal for on-road use in the U.S. & Canada.

• EPA fines can exceed $10,000 for tampering.

• Off-road/competition use only disclaimer applies.

🔎 Check local laws before modifying your Ram 2500.
