Considering an EGR delete for your 6.7L Powerstroke? Here’s a complete, honest guide to help you understand the real benefits and potential risks. Whether you’re aiming for better performance, longer engine life, or simply curious, we'll walk you through everything you need to know.

What Does the EGR System Do on a 6.7L Powerstroke?

The Exhaust Gas Recirculation (EGR) system on the 6.7L Powerstroke is designed to reduce nitrogen oxide (NOx) emissions. It works by redirecting a portion of exhaust gases back into the intake manifold to lower combustion temperatures and reduce harmful emissions.

However, over time, the EGR system can cause significant issues, such as:

• Carbon buildup in the intake manifold

• Reduced engine performance

• Higher maintenance costs due to failing EGR components

Many owners experience sluggish acceleration, lower fuel economy, and costly repairs as a direct result of EGR-related problems.

Pros of 6.7 Powerstroke EGR Delete Kits

👉 Increased Horsepower and Torque

Deleting the EGR system allows the engine to breathe cleaner, cooler air, enhancing combustion efficiency. On average, owners report a gain of 5-15 horsepower and improved throttle response, making towing and off-road driving noticeably smoother.

👉 Improved Fuel Economy

Without the EGR system recirculating exhaust gases, the engine can operate more efficiently. Some truck owners have seen fuel economy improvements from 15 MPG to 17-18 MPG in mixed driving conditions, resulting in tangible fuel savings over time.

👉 Reduced Maintenance Costs

The EGR system is prone to failures such as clogged valves and cooler leaks. By eliminating it, you can avoid expensive repairs that often range from $500 to $2,000. Less soot buildup also means fewer intake cleanings and longer-lasting components.

👉 Cleaner Engine Operation

Without exhaust gases re-entering the combustion chamber, there is significantly less carbon buildup inside the engine. This can lead to:

• Longer engine life

• Better performance retention over time

• Reduced oil contamination

Cons of 6.7 Powerstroke EGR Delete Kits

❌ Legal and Compliance Issues

Deleting the EGR system violates EPA federal emissions regulations. Using a deleted truck on public roads can lead to serious penalties, including:

• Fines up to $2,500 per violation

• Failed vehicle inspections, particularly in emissions-heavy states like California and New York

❌ Higher Exhaust Gas Temperatures (EGT)

The EGR system helps lower combustion temperatures. Removing it can cause a noticeable increase in EGTs, which can:

• Overstress the turbocharger

• Cause premature piston and valve wear

• Lead to head gasket failures if not properly monitored

Installing an EGT gauge and maintaining proper tuning is critical after an EGR delete.

❌ Risk of Engine Knocking

Changes in combustion dynamics can cause pre-ignition or "engine knock." This can lead to:

• Piston damage

• Rod bearing wear

• Catastrophic engine failure if not addressed early

Proper custom tuning significantly reduces this risk.

❌ High Initial Costs

While an EGR delete kit itself may only cost $200-$300, full implementation often requires:

• Tuner/Programmer: $500-$1,200

• Professional Installation: $300-$500

• Additional Modifications: Coolant reroute kits, upgraded sensors

Total project costs can quickly surpass $1,000-$2,000.

❌ Reduced Resale Value

Modified trucks are harder to sell, especially in areas with strict emissions laws. Resale value can drop by 10%-20%, and restoring the truck to stock form can be complex and costly.

Best Practices After EGR Delete: What Else Should You Upgrade?

Once you’ve removed the EGR system from your 6.7L Powerstroke, you're only halfway to unlocking the engine’s full potential. To ensure long-term reliability and performance, consider upgrading the following components:

• EGT Monitoring System: Removing EGR can increase exhaust gas temperatures. Installing a reliable EGT sensor helps you detect heat spikes and prevent turbo or piston damage.

• Custom ECU Tuning: A high-quality tune isn’t optional—it’s essential. Proper tuning not only keeps check engine lights off but also optimizes fuel delivery and combustion timing for safer performance.

• Coolant Reroute or Upgrade: Without EGR coolant flow, some trucks may experience minor cooling imbalances. Upgrading hoses or adding a bypass system can stabilize temperatures under load.

• DPF & DEF Delete Combo (Off-Road Use Only): Pairing your EGR delete with a DPF/DEF delete results in the cleanest airflow possible, giving you the best efficiency and throttle response.

⚙️ Recommended Setup: EGR Delete + ECU Tune + EGT Sensor = Safer Power Gains

This combination not only extends engine life but also ensures you’re making the most of your investment.

Conclusion: Should You Delete the EGR on Your 6.7 Powerstroke?

Deleting the EGR system offers real performance and reliability benefits, but carries significant legal and financial risks. If you primarily use your truck off-road or in non-regulated environments, a delete might be worth considering. However, if you rely on your truck for daily commuting or need to pass emissions tests, it’s better to explore legal performance upgrades.

Make an informed choice based on your needs and circumstances.

FAQs About EGR Delete Kits for 6.7 Powerstroke

Q1: Is EGR delete legal in my state?
A1: In most cases, it is illegal for on-road use. It may be allowed for off-road or racing vehicles.

Q2: How much horsepower can I realistically gain?
A2: Deleting the EGR system typically adds around 5-15 HP, depending on other modifications and tuning.

Q3: Will my truck last longer after an EGR delete?
A3: If tuned correctly and properly maintained, deleting the EGR can extend engine life by reducing soot buildup.

Q4: Can I reinstall the EGR system later?
A4: Technically yes, but it can be expensive and labor-intensive to source and reinstall OEM components.

Q5: Will deleting the EGR affect my fuel economy?
A5: Many users experience improved MPG, typically 1-3 more miles per gallon with proper tuning.

Q6: Will an EGR delete void my factory warranty?
A6: Yes. Removing emissions components like the EGR system will typically void all or part of your powertrain warranty. Make sure you’re comfortable with this trade-off before proceeding.

Q7: Can I legally use my truck with an EGR delete on public roads?
A7: In the U.S., no. Federal law prohibits tampering with emissions systems on vehicles used on public roads. EGR delete kits are strictly for off-road or competition use unless you are in a non-regulated territory.

Q8: What’s the difference between an EGR delete and an EGR block-off plate?
A8: An EGR delete removes all components (valve, cooler, etc.), while block-off plates only seal off the EGR passage without removing parts. Full deletes offer better airflow and performance but require tuning.

Q9: Can I still pass inspection after an EGR delete?
A9: In most emissions-regulated states, no. Your truck will likely fail an OBD-II scan or visual inspection if emissions components have been removed or disabled.
