A 6.7 Cummins delete offers pros like improved performance, fuel economy, and reduced maintenance, but comes with significant cons, including increased emissions, voided warranties, legal risks, and potential failure of emissions tests.
When you want to delete your 6.7 Cummins engine, it's important to consider both advantages and drawbacks. Read our guide for the pros and cons of deleting your 6.7 Cummins engine.
Pros of a 6.7 Cummins Delete
- More Power, Better Drive
Removing the 6.7 Cummins EGR, DPF, and DEF systems can significantly boost horsepower and torque, leading to better acceleration, faster throttle response, and overall improved engine performance.
- Go Further on Less
With fewer restrictions in the exhaust system, the engine can operate more efficiently, which may result in improved fuel economy, particularly under heavy load or towing conditions.
- Engine Life Longer
A delete reduces strain on the engine, as components like the DPF and EGR can cause clogging and carbon buildup. This leads to less frequent repairs and a longer engine lifespan.
- Easier Maintenance
The removal of emissions components eliminates the need for costly repairs and maintenance related to EGR, DPF, and DEF system failures. The truck becomes simpler to maintain.
- Better Towing and Hauling Capability
With more power and less exhaust restriction, a deleted 6.7 Cummins engine performs better under heavy towing and hauling conditions, making it more efficient for work-related tasks.
Cons of a 6.7 Cummins Delete
- Legal and Environmental Risks
Removing emissions components violates federal and state regulations. This can result in fines, penalties, and legal consequences, as well as increased environmental impact due to higher emissions.
- Warranty and Insurance Issues
A delete voids the vehicle’s manufacturer's warranty and can complicate insurance claims. Insurers may also raise premiums, or refuse coverage altogether due to the modification.
- Hotter Exhaust Temperatures
Without emissions controls, the exhaust can get hotter. This can put extra stress on the engine, but if you tune the truck properly, it can usually be handled. Still, it’s a risk some people are willing to take for better performance.
Considerations Before Deleting
Know Your Local Laws: Check local emissions laws, as deleting your emissions systems may be illegal in some areas, leading to fines or penalties.
Cost and Installation: The delete process can be costly, including parts, installation, and tuning. Improper installation could cause engine problems, so weigh the performance benefits against the cost.
