What Is a Delete? What Systems Are Involved?
If you’re just getting into diesel performance, the term “delete” might sound a little mysterious at first. But in the world of 6.7 Powerstroke tuning, it’s a common and often essential upgrade.
A “delete” simply means removing factory-installed emissions components that restrict your engine—specifically the DPF (Diesel Particulate Filter), EGR (Exhaust Gas Recirculation), and DEF (Diesel Exhaust Fluid) systems. These parts are designed to reduce emissions, but they also limit airflow, increase backpressure, and create reliability headaches.
What Is a DPF (Diesel Particulate Filter)?
The DPF is a filter located in your exhaust system that traps soot from the engine. Over time, it clogs and requires forced regeneration (burning off the soot) or expensive replacements. When the DPF becomes clogged, your truck loses power, mileage suffers, and repairs can become costly quickly.
Deleting the DPF allows your 6.7 Powerstroke to exhale more freely. It significantly reduces exhaust backpressure, resulting in improved throttle response and cooler exhaust gas temperatures (EGTs).
What Is an EGR (Exhaust Gas Recirculation)?
The EGR system recirculates a portion of the exhaust gas back into the engine's intake. This lowers combustion temperatures and reduces NOx emissions—but at a cost.
EGR systems are notorious for introducing carbon and soot directly into your intake manifold, which can lead to gummed-up valves, rough idling, and eventually, full-on engine issues. Deleting the EGR helps your 6.7 Powerstroke engine stay cleaner, run cooler, and avoid premature wear.
What Is a DEF (Diesel Exhaust Fluid) System?
DEF is a fluid injected into your exhaust stream to break down nitrogen oxides (NOx) in the SCR (Selective Catalytic Reduction) system. While effective for emissions, DEF tanks, injectors, and sensors are just more parts that can fail—and refilling DEF regularly adds up.
Deleting the DEF system reduces complexity, removes potential failure points, and is especially useful for off-road or heavy-duty applications.
Together, these deletes can transform your Ford Powerstroke. You’ll notice immediate improvements in power, driveability, and long-term reliability—especially if you're hauling, towing, or driving in harsh climates.
Everything You Need to Delete a 6.7L Powerstroke
So you're ready to get rid of the restrictions—what exactly do you need? Whether you drive a 2011 or a 2024 model, the core components required for a complete 6.7 Powerstroke delete are largely the same.
Below is your go-to checklist for a full Ford 6.7 delete kit setup:
✅ 1. DPF Delete Pipe
This is the main pipe that replaces your factory DPF and CAT. It bolts directly to your downpipe and rear exhaust, ensuring smooth and unrestricted exhaust flow.
A high-quality 6.7 DPF delete pipe is made from high-grade stainless steel, mandrel-bent, and welds cleanly to your factory system or aftermarket exhaust.
✅ 2. EGR Delete Kit
The EGR delete kit typically includes block-off plates, a coolant re-route hose or plug, and hardware to seal off the EGR valve and cooler.
Make sure the kit is year-specific. For example, the 2017–2019 Powerstroke uses different coolant routing than the 2020+ models. Fitment matters—don’t cheap out here.
✅ 3. DEF Delete Emulator (Optional but recommended)
Some setups include a DEF emulator or module to electronically disable the fluid injection system and associated sensors. While not always needed with proper tuning, it can add an extra layer of stability to your build.
✅ 4. Tuner with Custom Delete Tunes
No delete is complete without a proper tuner. The ECU must be reprogrammed to accept the removal of emissions systems—or else your truck will throw codes, derate power, or even go into limp mode.
Popular choices for Ford 6.7 delete kit tuners include:
- EZ Lynk AutoAgent
- MM3 Tuner with custom files
- HP Tuners with unlocked ECM (2020+)
Custom tunes also help you unlock horsepower on 6.7 Powerstroke—often boosting power by 60–100HP depending on the tune and mods.
✅ 5. Optional Add-Ons: Muffler, Cold Air Intake, or Downpipe
Want to quiet things down a bit? Add a high-flow muffler.
Looking for extra airflow? Drop in a cold air intake.
Replacing the restrictive downpipe? That’s an option too, especially for 2011–2016 trucks with tight bends.
Pro Tip: At SPETUNER, we offer all-in-one delete kits bundled by year (2011–2024), so you get every part you need without second guessing compatibility.
How to Install a DPF/DEF/EGR Delete (Step-by-Step)
Installing a full delete kit on your 6.7 Powerstroke is a serious job—but it’s completely doable with some mechanical knowledge and patience. Here's a straightforward breakdown of the process.
This guide assumes you're working on a Ford Super Duty with the 6.7L diesel engine, model year 2011 through 2024.
Note: Always work on a cold engine and wear proper safety gear. Disconnect the battery before starting.
Step 1: Prep Your Tools and Workspace
Clear your work area and gather essentials like:
Socket and wrench set
Pry bars and extensions
Torque wrench
Penetrating oil (for rusted bolts)
Jack stands or a lift (highly recommended)
It’s also helpful to have a code scanner and your new tuner ready to go.
Step 2: Remove the DPF and DEF Systems
Crawl underneath and start by removing the DPF and SCR assembly. This usually involves:
Disconnecting sensors and DEF lines
Unbolting the exhaust brackets
Dropping the full filter housing
If your kit replaces the DEF tank or injectors, disconnect those as well. Cap off any open lines.
Removing these bulky, restrictive components can take time—but once out, you’re clearing the path for real performance gains.
Step 3: Install the Delete Pipe and Components
Bolt in the DPF delete pipe where the old filter used to sit. It should align cleanly with the downpipe and tailpipe.
Install your EGR delete kit next. This may require:
Blocking off the EGR cooler ports
Rerouting coolant lines or plugging them
Removing the EGR valve altogether (depending on the year)
Follow your kit’s instructions carefully—each model year has slight variations.
Step 4: Flash Your ECM Using a Tuner
Connect your EZ Lynk, MM3, or HP Tuners device. Load your custom delete tune to remove emissions coding and optimize performance.
This is where the real magic happens: disabling EGR function, deleting DEF/DPF triggers, and boosting horsepower on your 6.7 Powerstroke.
Once flashed, your truck should no longer throw emissions codes.
Step 5: Start the Engine and Perform a System Check
Start the truck and let it idle. Watch for any check engine lights (you shouldn't see any with a proper tune).
Take a short test drive. Listen for leaks, monitor EGTs, and scan for DTCs.
You should feel improved throttle response, stronger acceleration, and smoother shifts.
Is Deleting Your 6.7 Powerstroke Worth It?
If you've dealt with a clogged DPF, failing sensors, limp mode, or constant regen cycles—then yes, deleting your 6.7 Powerstroke is absolutely worth it. But let's break it down beyond just frustration relief.
More Horsepower and Torque
Removing the DPF, EGR, and DEF systems eliminates major airflow restrictions. Combine that with a quality tune, and you're looking at a gain of 30 to 100+ horsepower on a 6.7 Powerstroke, depending on your setup.
That extra power translates into faster throttle response, quicker acceleration, and smoother towing performance. You’ll feel it instantly—especially under load or on hills.
Better Fuel Economy
Factory emissions systems create backpressure and force regen cycles, which waste fuel. Deleting them can result in gains of up to 3–5 MPG, especially on highways and long-haul routes.
This means fewer fill-ups, more range, and a noticeable drop in fuel costs over time—especially if you're running your truck hard.
Fewer Maintenance Headaches
Let’s be real—EGR valves get clogged, DPFs crack or clog, DEF tanks leak, sensors fail. Once these systems are gone, so are those problems.
You’ll avoid costly service visits and downtime. No more regen issues. No more DPF codes. No more DEF refills.
Longer Engine Life
Without EGR feeding soot back into your engine and without extreme exhaust temps from regen cycles, your 6.7 Powerstroke runs cleaner and cooler. This translates into less wear and tear—and potentially thousands of dollars saved in long-term repairs.
