What Makes Our 6.7 Cummins Delete Kit Different

Everything in the kit is built around the same goal: keeping the setup clear and the main components working together. The device handles the supported DPF and DEF functions, and the exhaust parts complete the physical side of the installation.

KEEP YOUR FACTORY ECU

The ECU stays in the truck. You do not need to remove it, send it away, or flash new software onto it as part of our setup.

ONE KIT. ONE CLEAR PROCESS.

Everything in the kit has a specific job. The device takes care of the supported DPF and DEF functions, the supplied connections get it into the truck’s setup, and the exhaust parts replace the required section.

TALK TO PEOPLE WHO KNOW THE PRODUCT

If you have a question about fitment, installation or the kit itself, you are talking to people who work with these Cummins setups every day. You do not have to figure everything out from a product listing.

How the tuneDiesel kit work

The kit consists of the device, wiring harness, and exhaust replacement parts together in one setup. The factory ECU stays in the truck, and you just install the parts supplied with the kit. If needed, our reliable team of motorheads is ready to take your call and answer any questions you may have.

The Tuning Module

High-Flow Exhaust Pipes

Replace restrictive factory sections with our heavy-duty, mandrel-bent steel pipes. Designed to drop exhaust gas temperatures (EGTs) and bolt perfectly into your truck's original factory hangers.

OEM-Grade Wiring Harness

No splicing or soldering. We provide weatherproof, corrosion-resistant connectors that ensure a flawless, long-lasting link between your truck's electrical system and the tuner.

VIEW FULL PROCESS

Step 1: Safe Disassembly

Always start by disconnecting the negative battery terminal. Then, carefully unplug the factory sensors from the stock exhaust system, retaining the original bolts for the new setup.

Step 2: Bolt-On Exhaust Swap

Drop the heavy, restrictive factory exhaust sections. Because our pipes are precision-machined for your specific truck bed and cab size, they bolt right up to the original mounting points without any modifications.

Step 3: Connect the Module

Mount the tuning module securely in the engine bay away from extreme heat sources. Plug the custom harness directly into the designated OEM ports—it only fits one way, making it foolproof.

Step 4: Fire It Up

Double-check all connections, reconnect the battery, and start the engine. You will immediately notice a deeper exhaust tone, clearer dashboard, and sharper throttle response.
