Why 2020-2024 6.7L Powerstroke Owners Look for Delete Kits

Ford's third-generation 6.7L Powerstroke — introduced for the 2020 model year — brought legitimate improvements in horsepower, torque, and towing capacity. But alongside those gains came a significantly tighter emissions calibration. Ford tightened ECU fault thresholds starting in 2020 to comply with updated EPA Tier 4 standards, meaning the PCM (Powertrain Control Module) is far more sensitive to even minor deviations in emissions sensor readings than it was on 2011–2019 trucks.

The practical result? Owners report more frequent DPF regeneration cycles, DEF consumption that climbs quickly under hard towing or high-load conditions, and EGR-related check engine lights that appear earlier than expected. The CP4.2 injection pump was also replaced with a CP4.2b in the Gen 3, and the overall fuel system calibration runs leaner, which can contribute to higher exhaust gas temperatures (EGTs) during sustained regen events.

Bottom line: the 2020+ 6.7 Powerstroke is a capable, powerful diesel — but it's also a truck that rewards owners who understand its emissions systems and know when those systems are working against them.

2020-2024 Emission System Overview

The Gen 3 6.7L Powerstroke carries a full four-layer emissions stack:

  • DOC — Oxidizes hydrocarbons and CO in the exhaust stream.
  • DPF — Traps soot and particulate matter. Requires active and passive regeneration cycles to clean itself.
  • SCR — Uses DEF (Diesel Exhaust Fluid / AdBlue) to convert NOx into nitrogen and water via a urea injection process.
  • EGR — Routes a portion of exhaust gas back into the intake manifold to lower combustion temperatures and reduce NOx at the source.

What's New vs. 2011–2019

On earlier Gen 2 trucks, sensors would tolerate a wider band of deviation before setting a fault code. On 2020+ trucks, faults trigger faster and with less warning, which means a partially failing DPF or marginal EGR cooler can put your Super Duty in limp mode before you ever see a symptom.

System / Component 2011–2019 (Gen 2) 2020–2024 (Gen 3) Delete & Tuning Implications
NOx Sensor Tolerance Wider deviation band Extremely tight calibration Requires Gen 3 specific NOx emulators to avoid instant derate.
EGR Cooler Design Standard flow geometry Redesigned cooler & valve seat Prone to carbon sticking; requires updated Gen 3 bypass gaskets.
DPF Pressure Limits Standard monitoring Tighter differential limits False trips are common; demands precise PCM tuning to disable.
Injection Pump CP4.2 CP4.2b (Leaner calibration) Higher baseline EGTs during regen; delete significantly cools EGTs.

Common failure points unique to 2020–2024:

  • DPF pressure differential sensor false trips (common on trucks with high tow hours).
  • SCR efficiency codes (P20EE, P2201) driven by tight NOx sensor calibration.
  • EGR valve sticking due to carbon buildup on the updated valve seat design.
  • DEF dosing injector fouling at higher mileage.

Complete Delete Kit Contents for 2020-2024

A proper 2020–2024 6.7L Powerstroke delete kit is not the same as a kit built for 2011–2019 trucks. Fitment differences are real, and using an older-gen pipe or EGR hardware will cost you time and money. Here's what a complete kit for the Gen 3 platform includes:

DPF Delete Pipe — Gen 3 Fitment Specs

The delete pipe replaces the factory DPF/DOC/SCR assembly with a high-flow straight pipe. For 2020–2024 trucks, look for a pipe designed to match the factory downpipe outlet diameter and exhaust hanger positions on the Gen 3 frame. Most quality kits for this platform use 4" or 5" mandrel-bent stainless steel construction. The 5" downpipe-back option is particularly popular for owners who tow heavy or want to aggressively reduce EGTs.

EGR Delete Hardware — Updated Gasket Set

The 2020–2024 EGR system uses an updated cooler and valve configuration compared to Gen 2 trucks. A correct 6.7 Powerstroke EGR delete kit for this application includes CNC-machined billet aluminum block-off plates, an updated gasket set matching the Gen 3 EGR cooler ports, and in most cases a coolant flow-through bypass plate to keep engine temps stable after the cooler is removed.

DEF / SCR Bypass + NOx Sensor Emulator

Because the 2020–2024 ECU runs tighter NOx sensor tolerances, simply removing the SCR hardware without addressing the NOx sensor signal will immediately set fault codes and put the truck in derate. A quality Gen 3 delete kit includes either a NOx sensor emulator or resistor setup calibrated for the 2020+ sensor positions. This is one of the most important differences between buying a 2020–2024-specific kit versus adapting an older kit.

2020–2024 Compatible Delete Tuner

This is non-negotiable. A diesel performance tuner designed specifically for the 2020–2024 PCM must be included. The Gen 3 PCM uses updated software architecture that older tuning solutions may not fully support. The tuner handles DPF regen disable, EGR disable, DEF injector disable, NOx/EGT sensor table removal, and recalibrated fueling maps. Many owners on the 2020+ platform also run transmission tuning at the same time due to the 10-speed SelectShift, which is sensitive to torque changes.

Model Year Fitment Details

2020 / 2021 / 2022 Compatibility Notes

The 2020, 2021, and 2022 model years share the same Gen 3 engine architecture, exhaust routing, and PCM software generation for delete purposes. Hardware fitment (DPF pipe, EGR block-off) is consistent across these three model years on both pickup and cab-and-chassis configurations. Confirm whether your truck is a 4x2 or 4x4 configuration, as rear axle placement can affect exhaust routing clearances.

2023 / 2024 Updates — Any Hardware Differences?

Ford made incremental software calibration updates for 2023 and 2024 that affect tune compatibility. Some early 2020–2022 tune files will not work correctly on a 2023 or 2024 PCM without a version update. Hardware (delete pipe, EGR kit, NOx emulator) fitment remains the same between 2022 and 2024. Always confirm your tuner supports 2023/2024 PCM revisions before purchasing. Reputable kits from EngineGo are verified for the full 2020–2024 range.

Install Difficulty vs. 2011-2019

If you've deleted a 2011–2019 6.7 Powerstroke before, the 2020–2024 process will feel familiar but with a few added steps that demand more attention.

What's harder on the Gen 3:

  • The EGR cooler assembly on the 2020+ engine is positioned slightly tighter against the firewall on cab-and-chassis configurations, adding wrench clearance challenges.
  • The updated exhaust sensor wiring harness runs differently, and you'll need to properly loop out or emulate the downstream NOx and EGT sensor signals.
  • The 10-speed automatic transmission on most 2020+ Super Duties benefits from a transmission tune alongside the engine tune. If you skip this, you may experience shift quality issues after increasing torque output.

Tune Flash Process for 2020–2024 ECU

Always flash the ECU before removing any hardware. This prevents limp mode during the teardown process. For the Gen 3 platform, most supported tuners use an OBD-II bench flash or direct PCM flash approach. Follow the tuner manufacturer's firmware confirmation steps for 2023/2024 software revisions. After hardware installation is complete, a second flash may be needed to finalize idle relearn and fueling calibration. \ \ For a complete one-stop solution on the Gen 3 platform, the diesel all-in-one delete kits bundle the pipe, EGR hardware, emulator, and tuner together — reducing the risk of component mismatch across suppliers.

Expected Performance Gains

Eliminating the restrictive emissions hardware and applying a dedicated tune wakes up the Gen 3 Powerstroke. Here are the real-world results you can expect:

Performance Metric Expected Gains  Real-World Impact
Horsepower +40 to +80 HP  Noticeably sharper throttle response and highway passing power.
Torque +80 to +120 lb-ft Massive improvement in mid-range pulling power, especially when loaded.
Fuel Economy +1.5 to +3.0 MPG Eliminates passive/active regen fuel penalty and reduces EGR pumping losses.
Exhaust Temps (EGTs) Significant Reduction Much safer sustained towing temperatures due to improved exhaust scavenging.
Overall Reliability High Total elimination of DPF clogging, SCR codes, DEF failures, and EGR carbon buildup.

FAQ

Does the 2020–2024 6.7 Powerstroke need a different delete kit than the 2011–2019?

Yes. The Gen 3 has different NOx sensor positions, updated EGR hardware, and a revised PCM that requires 2020+ specific tuning. Using a 2011–2019 kit on a 2020+ truck will result in fitment issues and tune incompatibility.

Will I still get a check engine light after the delete?

Not if the kit is installed correctly with the appropriate NOx sensor emulators and a compatible tune. The tuner disables all emissions-related fault monitors in the PCM.

Can I still use my truck for towing after a delete?

Absolutely. In fact, most owners report improved drivability and towing confidence after a full delete + tune due to lower EGTs, better throttle response, and elimination of regen events that can interrupt towing at low speeds.

What's the difference between a DPF-only delete and a full all-in-one delete kit?

A DPF-only delete removes the particulate filter and pairs with a tune to disable regen. A full all-in-one kit also removes the EGR system and DEF/SCR system, providing a more complete solution for reliability and performance. For 2020–2024 trucks, most experienced diesel builders recommend the full kit.

Is a tune absolutely required?

Yes, without exception. Running the 2020+ 6.7 Powerstroke without the factory emissions hardware but without a supporting tune will trigger immediate fault codes, derate, and potential limp mode.
