When you install the delete tune, your truck will no longer have emission related codes or warnings. 

This includes all

1) “See Dealer” codes

2) Check engine codes

3) “Exhaust system service required” codes

4) Limp Mode codes

5) Other emissions related diagnostic codes

By deleting the factory emissions system that’s been suffocating your diesel, you’ll notice a night-and-day difference right away.

• Better performance: your truck runs better in every way, starting with throttle response.
• Better fuel economy: an average 5 mpg increase.
• Pays for itself: over time, the fuel savings alone cover the cost of the kit.
• Fewer shop visits: no more costly trips to the dealer for emissions repairs.
• Peace of mind: your truck no longer has a ticking time bomb attached to it.

Our custom tunes include multiple power levels, so you can run your truck the way you want. The included DSP5 switch lets you change between its 5 levels in real time (also known as “shift on the fly”).

EFI Live power settings:

• Level 1 (Stock): no added HP. Ideal for daily driving and towing.
• Level 2: +30 HP. Ideal for daily driving and light towing.
• Level 3: +65 HP. Ideal for daily driving.
• Level 4: +100 HP. Ideal for performance applications.
• Level 5: +130 HP. Ideal for performance applications.

The bundle includes:

• EFI Live delete tuner with our custom delete tunes, plus all required accessories (tunes emailed, not preloaded)
• Rotary switch to change power levels
• 4" full exhaust system
• Complete EGR delete kit

Optional add-ons:

• 5" full exhaust system upgrade
• Muffler system

The GM/Chevy Duramax 6.6L LMM Full Delete bundle will permanently upgrade your truck to work without the suffocating factory emissions system.

This means you can remove ALL emissions-related parts and sensors for good, including:

• DPF (Diesel Particulate Filter)
• DEF Tank (Diesel Exhaust Fluid)
• EGR System (Exhaust Gas Recirculation)
• CAT (Catalytic Converters, including DOC and NOx)

This is made possible by our custom delete tunes that wipe away the emissions system from your truck’s computer.

How it works

1. Plug in the tuner. Connect it to your truck’s OBD-II port, located under the steering wheel.
2. Load the tune. Follow the installation instructions we send you. Tech support is available if you need a hand.
3. Remove the parts. Once the emissions system is “deleted” from the programming, you can remove everything holding your diesel back.

What’s in the kit

• Full exhaust system: replaces your factory exhaust, including the DPF and CAT.
• EGR delete kit: lets you remove the factory EGR system, seal the openings, and reroute exhaust out the pipe.

Not tech savvy? Nervous about the software or frying your truck? No worries! Every order comes with a step-by-step instruction guide, and if you run into any issues, we’ve got your back. Contact us anytime and we’ll get it sorted.

• EFI Live tuner: takes a few more steps to install. See the Important for EFI Live tab for details.
• Exhaust system: bolts on with the bolts and clamps we provide. No welding, just basic tools you probably already own, like wrenches and ratchets.
• EGR delete kit: also fully bolt-on with no welding required. We’ll email you installation videos for these parts.

If you’re a complete fish out of water when it comes to working on your truck, we highly recommend having a shop do the install.
