We stock the tuning platforms and exhaust systems that unlock what your diesel already has inside. ### EFI Live & EZ LYNK Tuning for 6.7L Cummins (2013-2018) Both EFI Live Autocal V3 and EZ LYNK Auto Agent are proven delete tuners. The Autocal works standalone—no laptop needed after tuning. EZ LYNK offers the same DPF and EGR delete capability with lifetime support. Pick based on your workflow: EFI Live for simplicity, EZ LYNK for ongoing support and updates. The H&S Mini Maxx and RaceMe Ultra are solid alternatives if you want a different platform. All these tuners reprogram your factory ECM to eliminate DPF regen cycles and EGR operation, giving you cleaner exhaust flow and noticeable power gains. ### Complete Exhaust Systems & Delete Pipes Tuning works best with proper exhaust flow. Our 5" full exhaust systems and DPF & CAT delete pipes pair perfectly with any tuner. The delete pipe bypasses your DPF and catalytic converter entirely—a bolt-on that's essential for maximizing tuning performance on your 2013-2018 6.7L. ### What Should You Buy First? Start with a tuner (EFI Live or EZ LYNK) if you're new to Cummins tuning. Add the DPF delete pipe next—the combo is where you'll feel the real difference. A full 5" exhaust upgrade is the final step for maximum scoop. For more 6.7L performance options, check out 6.7L Cummins intake systems and turbo upgrades.

Is EFI Live or EZ LYNK better for my 2013-2018 6.7L Cummins?

Both are excellent. EFI Live Autocal V3 is plug-and-play with no computer required after initial tuning—great if you like simplicity. EZ LYNK Auto Agent 3 offers lifetime support, cloud backup, and easier tune adjustments if you want flexibility. Neither is objectively "better"—choose based on whether you prefer standalone simplicity or ongoing support access.

Can I delete my DPF without a tuner?

No. The DPF delete pipe is a mechanical bypass, but your factory ECM will still command regeneration cycles and throw fault codes. You need a tuner (EFI Live, EZ LYNK, H&S Mini Maxx, or RaceMe Ultra) to reprogram your engine computer and disable DPF logic entirely. Tuner + delete pipe = the correct combination.

Will deleting my EGR hurt my engine?

EGR delete won't damage a stock engine, especially on the 6.7L Cummins which runs relatively cool. Deleted EGR means lower intake temps, less carbon buildup, and more consistent air density—all positives for reliability. Many high-mileage Cummins owners delete EGR specifically to reduce maintenance. That said, any modification carries risk; make sure you understand local laws first.

What's the difference between CSP4 and CSP5 delete tunes?

CSP (custom speed performance) levels refer to delete tune aggressiveness. CSP4 is moderate—solid power gains with a balanced approach to engine stress. CSP5 is more aggressive. For a stock 6.7L, CSP4 or CSP5 both work fine. Choose CSP4 if you tow heavy or want conservative tuning; go CSP5 if you're chasing peak power and have supporting mods like intake or cooling upgrades.

Do I need a full 5-inch exhaust or just the delete pipe?

The delete pipe alone eliminates backpressure and allows tuning to work. A full 5" exhaust system is the upgrade—larger diameter piping, mandrel bends, and a performance muffler maximize flow and give you that deep diesel tone. If budget is tight, start with the delete pipe and tuner. Add the full system later when you're ready for the complete package.

Will a delete tune affect my warranty?

Yes. Any ECM reprogram voids your factory Dodge warranty immediately. Dodge can refuse warranty claims on engine/emissions-related issues once they detect a tune. This is why many owners keep their factory tune file backed up—you can always reflash to stock before dealer service. Know this going in.

How much HP/torque will I gain from delete tuning on my 6.7L?

Expect 50-100+ hp and 100-150+ lb-ft torque gains depending on your tuner choice and tune file aggressiveness. EFI Live and EZ LYNK are conservative but reliable. H&S Mini Maxx and RaceMe Ultra push harder numbers. Real-world gains depend on supporting mods (intake, exhaust, cooling) and your tune level. A tuner + delete pipe combo on a stock truck will feel noticeably quicker—no dyno required to tell the difference.
