Looking to boost your 6.7 PowerStroke’s performance and fuel economy? Delete kits promise impressive gains, but choosing the right one is critical for your truck’s longevity and reliability. Whether you’re considering a simple EGR delete or a comprehensive emissions system overhaul for off-road use, this guide breaks down everything you need to know about the top options available, their performance benefits, and important considerations before making your decision.
Understanding 6.7 PowerStroke Delete Kits
A delete kit for the 6.7 PowerStroke essentially removes or bypasses certain emission control systems on your diesel engine. These typically include:
- Diesel Particulate Filter (DPF): Captures soot and particulate matter
- Exhaust Gas Recirculation (EGR) system: Reduces nitrogen oxide emissions
- Diesel Exhaust Fluid (DEF) system: Uses urea injection to neutralize emissions
Any modification to these systems requires proper ECU tuning to prevent error codes and ensure your engine runs correctly. Without proper tuning, your truck could experience serious performance issues or even engine damage.
Important Legal Disclaimer
Before diving into specific products, you should understand that removing emissions equipment from road vehicles is federally illegal in the United States. The EPA and Department of Justice actively enforce these regulations with substantial penalties including fines up to $5,000 per component and potential criminal charges.
Delete kits are designed and marketed exclusively for off-road and competition use where different regulations may apply. Modifying your daily driver could result in:
- Heavy fines and penalties
- Voided vehicle warranty
- Failed emissions inspections
- Insurance coverage issues
- Potential registration problems

Performance Benefits and Specifications
Horsepower and Torque Gains
Delete kits can provide substantial performance improvements when properly tuned:
- EGR Delete Only: 10-20 HP gain
- DPF Delete: 30-50 HP gain
- Combined EGR + DPF Delete: 60-80 HP gain
- Full Delete with Tuning: 80-150+ HP gain
These power increases come from reducing exhaust backpressure, eliminating restrictive emissions components, and optimizing fuel delivery through custom tuning.
Fuel Economy Improvements
One of the most significant benefits reported by users is improved fuel economy:
- Stock 6.7 PowerStroke: Typically averages 16 MPG
- After DPF Delete: 20-21 MPG average
- Improvement: 4-5 MPG increase (approximately 30% better)
This efficiency boost comes from eliminating the fuel-consuming DPF regeneration cycles and reducing the restrictive exhaust flow that creates backpressure in the system.
Installation Costs and Considerations
Labor Costs
If you’re not installing the kit yourself, professional installation typically costs between $400-$1,800 depending on your location and the complexity of the kit:
- Experienced diesel mechanic: 4-6 hours
- Less experienced installer: Up to 8 hours
- EGR delete only: 2-3 hours
- Full delete (EGR + DPF): 5-7 hours
Total Project Costs
For budgeting purposes, a complete 6.7 PowerStroke delete project typically costs:
- DIY Installation: $1,500-$3,000 (parts only)
- Professional Installation: $2,000-$4,500 (parts + labor)
- Premium Kits with Support: $3,000-$5,000+
These costs vary based on model year, components selected, and whether you choose premium support packages.

Model Year Considerations
2011-2014 Models
The earliest 6.7 PowerStroke generations have simpler emissions systems with fewer sensors, making them more compatible with basic delete kits and tuners. These trucks typically:
- Require less complex tuning
- Have more affordable delete options
- Work with a wider range of aftermarket tuners
2015-2016 Models
Ford updated the ECU and added more emissions sensors in these model years, requiring kits specifically labeled for 2015+ compatibility. Important differences include:
- Updated ECU programming requirements
- Additional emissions sensors
- More complex tuning needs
2017-2019 Models
These models introduced stricter emissions monitoring and more sensitive ECU programming, requiring precision tuning and high-quality delete kits. Key challenges include:
- Enhanced security features in the ECU
- More advanced emissions monitoring systems
- Fewer compatible tuning options
2020+ Models
The newest PowerStroke models have the most complex emissions systems and encrypted ECUs, with limited tuning support available. These require:
- Specialized tuning tools with unlocking capabilities
- Premium delete kits designed specifically for these years
- Professional installation in most cases
Legal Performance Alternatives
If you’re concerned about the legal implications of delete kits, several legitimate performance upgrades can improve your 6.7 PowerStroke without tampering with emissions equipment:
Cold Air Intake Systems
High-quality cold air intakes provide measurable gains without legal concerns:
- S&B Filters: 37-39% airflow improvement with 99%+ filtration efficiency
- Banks Power: Cross-linked polyethylene construction with high-temperature resistance
- No Limit Fabrication: Aluminum construction with reinforced silicone couplers
These systems typically provide 5-10 horsepower gains, 1-3 MPG improvement, and faster turbo spool-up.
Intercooler Upgrades
Cold-side charge pipe upgrades address weak factory components:
- Sinister Diesel: Features 6061 aluminum construction with 400 PSI rated boots
- Some options are CARB legal for certain models (with EO# D-721-8)
These upgrades improve charge air cooling, reduce boost leak issues, and enhance overall performance while maintaining emissions compliance.

Installation Tips for Best Results
If you’re proceeding with an off-road delete kit, follow these best practices:
- Document everything before disassembly with photos and notes
- Use proper torque specifications for all fasteners
- Apply anti-seize compound to exhaust components
- Install a monitoring system like an EGT gauge
- Secure all wiring away from heat sources and moving parts
- Reset the ECU completely before installing new tunes
- Start with the mildest tune and progressively test more aggressive options
Taking your time during installation will prevent costly mistakes and ensure you get the maximum benefit from your delete kit investment.
The Bottom Line on 6.7 PowerStroke Delete Kits
For off-road and competition use, the best delete kit for your 6.7 PowerStroke ultimately depends on your specific model year, budget, and performance goals. Diesel Dudes offers the most comprehensive solution with proven results, while other manufacturers provide specialized options for different needs and price points.
However, for daily drivers and road-legal vehicles, the significant legal risks and potential penalties make emissions equipment removal a costly gamble. Consider legal performance alternatives like cold air intakes and intercooler upgrades that can deliver meaningful improvements without the legal exposure.
Whatever path you choose, work with reputable companies, invest in quality components, and ensure proper installation for the best results with your PowerStroke.
