NO MORE EMISSIONS CODES

When you install our custom delete tune, your truck will no longer show the check engine light or other emissions-related warnings, including:

  • “See Dealer”
  • “Exhaust system service required”
  • Limp mode and any other emissions-related codes

BENEFITS

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.

TUNE POWER SETTINGS

Our custom tunes include multiple power levels, so you can run your truck the way you want. On 2007–2018 trucks, the included CSP4/5 switch lets you change between levels in real time (also known as “shift on the fly”).

2007–2009 Ram 6.7L power settings (shift on the fly):

  • Level 1 (Stock): no added HP. Ideal for daily driving, towing and the best mpg.
  • Level 2: +65 HP. Ideal for daily driving and towing.

WHAT'S INCLUDED?

The package includes:

  • EFI Live AutoCal delete tuner with all required cables and accessories
  • Our custom delete tune, built for your specific truck (emailed, not preloaded; needs a Windows 10 or newer computer to install)
  • DSP5 switch to change power levels on the fly
  • Step-by-step installation instructions, emailed to you

HOW DOES IT WORK?

The EFI Live delete tuner 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. Load the tune onto your EFI Live. Use the free EFI Live V8 software to transfer the delete tune from your computer to your EFI Live. We’ll send you basic instructions. You’ll need a Windows 10 or newer computer (no Macs or older PCs).
  2. Plug in the tuner. Connect your EFI Live to your truck’s OBD-II port, located under the steering wheel.
  3. Install the tune. Follow the installation instructions we send you. Tech support is available if you need a hand.
  4. Remove the parts. Once the emissions system is “deleted” from the programming, you can remove everything holding your diesel back.

You’ll also need a DPF delete pipe: install one after you install the tune. The only exception is older Duramax models that never had a DPF. Shop DPF delete pipes and exhaust systems

Want everything in one kit? Our full delete bundles include this tuner, a delete pipe and an EGR delete kit. Find your full delete bundle

IMPORTANT INSTALLATION INFORMATION

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. Open a support ticket and we’ll get it sorted.

  • EFI Live tuner: you’ll load our custom delete tune onto the tuner from your computer before plugging it into your truck. See the How does it work? tab for the steps.

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.

COMPUTER NEEDED. MINIMUM REQUIREMENTS

To make sure your EFI Live delete tuner runs without problems, check that your computer meets these minimum requirements:

  • Software: EFI Live Scan & Tune V8, free to download from EFI Live’s website
  • Operating system: a PC or laptop running Windows 10 or 11
  • Not compatible with: Mac or Linux
  • Connectivity: one available USB port to connect the tuner
  • Display: a standard monitor or laptop screen
  • Storage: at least 1 GB of free hard drive space

CAB & CHASSIS INFORMATION

Cab & Chassis trucks get a single +50 HP tune file, not the DSP5 switch with multiple power levels.

How to tell if you have a Cab & Chassis truck: your registration sticker, usually on the driver’s door, says “Incomplete Vehicle” below the VIN. Most Cab & Chassis trucks are 4500 and 5500 models.

Single fuel tank? If your Cab & Chassis truck has a single fuel tank, please contact us at (888) 830-2588 before purchasing, since certain model years aren’t compatible.

  • Express: 3–4 business days, available at the end of checkout

Alaska, Hawaii, and some Canadian locations are subject to additional freight charges.

The EFI Live Autocal V3 delete tuner for 2007–2021 Ram 6.7L Cummins permanently wipes the factory emissions system from your ECM — ending DPF regen cycles, DEF headaches, EGR soot, and every "See Dealer" code, check engine light, "Exhaust system service required" alert, and limp mode trigger that's been lighting up your dash.

It plugs into your OBDII port and downloads a custom delete tune straight to the ECM. That tune wipes the emissions programming so you can remove the DPF (Diesel Particulate Filter), DEF tank, EGR system, and CAT (including the DOC and NOX). You'll still need to install a DPF delete pipe after the tune. Owners report a 5 MPG increase on average, and the kit pays for itself in fuel savings before you even count the dealer trips you'll skip.

In the box: the EFI Live Autocal with all required cables and accessories (unlock cables for 2018+ models), a custom delete tune built to your truck, a CSP4/5 switch for shifting power on the fly on 2007.5–2018 models, transmission tuning for the 68RFE, and step-by-step instructions emailed to you. The 2007–2018 tune carries +0, +65, +100, and +130 HP levels; 2019–2021 runs +0, +45, +70, and +100 HP without shift-on-the-fly. Cab & Chassis 4500/5500 trucks get a single +0 HP file — confirm before ordering.

Fits 2007–2021 Ram 2500/3500/4500/5500. The tune is built to order on a Windows 10 or 11 PC; allow 1–2 business days to build. Call (888) 830-2588 for support.

For off-road/competition use only.

Frequently Asked Questions

Didn’t find what you were looking for? Reach out below!

A delete tuner is a device that reprograms your truck’s ECM (computer) to turn off emissions systems like the DPF, EGR, and DEF, allowing your truck to run without those components.
You MUST remove your DPF (Diesel Particulate Filter), as the filter will clog and stop all exhaust flow when shut off. 

You will no longer need DEF (Diesel Exhaust Fluid), and you may remove your DEF tank if you wish, or it can sit empty. The EGR may remain as is, but we recommend removing the physical parts as well.
Quite the opposite. In fact, many customers report improved engine life, smoother shifting, and better fuel economy (typically 3-5 MPG gains) when using a quality delete tuner.
The tuner is the hardware device. The tune is the software file that gets uploaded to your truck’s ECM. Your delete tuner includes a delete tune when you purchase from us.
Yes. Any emissions-related modification, including tuning, can void the manufacturer’s warranty. Many customers wait until after their warranty expires before deleting.
Not necessarily. Many of our customers install their delete tuner themselves in under 30 minutes. We include easy-to-follow instructions, and our support team is available if you need help.
No. Delete tuners disable emissions systems, so your truck will not pass emissions tests in areas where they're required. Some states have exemptions (e.g. heavy-duty or rural-use trucks).
Yes. However, in most cases you will have to have the ECM flashed at the dealership. If this is a concern, contact our team and we can explain further.
Yes. All delete tunes are VIN specific and will only work on one truck. The tuner (hardware device), may be used on multiple vehicles for diagnostic or monitoring purposes where applicable.
We offer lifetime customer support, step-by-step install guides, and remote help from our tuning team. You're never left hanging, even after the sale.
