These additional expenses can include upgrading the turbocharger, fuel system, or transmission components. Make sure to research and budget for any necessary upgrades.
- Calculate the total cost: Add up the costs of the delete kit, labor (if applicable), DIY tools and resources, and any additional components to determine your overall budget for the project.
- Evaluate potential long-term savings: While the initial costs of a 6.7 Cummins delete can be significant, it’s essential to consider the potential long-term savings. Improved fuel efficiency and reduced maintenance expenses can help offset the initial investment over time. Calculate the potential return on investment to determine if the deletion is a financially viable option for you.
- Assess the risks and drawbacks: Before moving forward with a 6.7 Cummins delete, weigh the potential risks and drawbacks, such as voiding your warranty, legal ramifications, and environmental impact. Ensure that you’re prepared to accept these risks and that the benefits of the deletion outweigh the potential consequences.
By following these steps and creating a well-researched budget, you can effectively plan for the costs associated with deleting a 6.7 Cummins engine and make an informed decision about whether this modification is right for you.
Reasons for Deleting a 6.7 Cummins Engine
There are several reasons why truck owners might choose to delete the emission control systems of their 6.7 Cummins engine. Some of the primary motivations include:
Deleting the EGR, DPF, and DEF systems can lead to noticeable gains in horsepower and torque. These performance improvements are often the most attractive aspect of deleting a 6.7 Cummins engine, as they can enhance the overall driving experience and the vehicle’s towing and hauling capabilities.
Increased fuel efficiency:
Removing the emission control systems can result in better fuel economy, as these systems can sometimes cause additional strain on the engine. With a delete, owners may experience a more efficient combustion process, leading to reduced fuel consumption.
Emission control systems, particularly the DPF, can require regular maintenance and cleaning to function correctly. By removing these systems, owners can eliminate the need for this maintenance and potentially save on long-term expenses.
Prolonged engine life:
The EGR system can introduce exhaust gases back into the engine, which can lead to carbon buildup and increased wear over time. By deleting the EGR system, owners may be able to prolong the life of their 6.7 Cummins engine.
Elimination of DEF expenses:
Diesel Exhaust Fluid (DEF) is used to help reduce emissions in diesel engines. However, the cost of purchasing DEF and maintaining the DEF system can add up over time. By deleting the DEF system, owners can eliminate these expenses.
While there are several potential benefits to deleting a 6.7 Cummins engine, it’s crucial to consider the risks and drawbacks as well. These can include voiding the vehicle’s warranty, legal and environmental consequences, and potential impact on resale value. Ultimately, each owner must weigh the pros and cons and decide if a delete is the right choice for their specific needs and circumstances.

Cost of Necessary Parts and Components
When planning a 6.7 Cummins delete, it’s essential to understand the costs associated with the necessary parts and components. Prices can vary depending on the brand, quality, and type of kit you choose. Here’s a breakdown of the primary components involved in the deletion process and their approximate costs:
EGR Delete Kit:
The Exhaust Gas Recirculation (EGR) delete kit includes the necessary components to block off or bypass the EGR system. EGR delete kits for a 6.7 Cummins engine typically range from $100 to $250.
DPF Delete Kit:
The Diesel Particulate Filter (DPF) delete kit involves removing the DPF and replacing it with a straight pipe or a performance exhaust system. DPF delete kits can vary widely in price, depending on the type of exhaust system chosen. Expect to pay anywhere from $300 to $1,000 for a DPF delete kit.
DEF Delete Kit:
The Diesel Exhaust Fluid (DEF) delete kit eliminates the need for DEF in your vehicle by altering the engine’s tuning or control module. DEF delete kits can range from $200 to $600, depending on the sophistication of the tuning device or module.
Deleting the emission control systems often requires a specialized engine tuner to recalibrate the engine’s computer. Engine tuners are available at various price points, typically ranging from $300 to $1,000 or more, depending on the brand and features offered.
In some cases, additional components such as upgraded fuel systems, turbochargers, or transmission parts may be necessary to accommodate the increased performance following a delete. These costs can vary widely depending on the specific components required and the quality of the parts chosen.
When budgeting for a 6.7 Cummins delete, it’s crucial to research and compares the various kits and components available on the market. Keep in mind that the quality of the parts can impact the overall performance and longevity of your vehicle, so it’s essential to choose components that offer the best balance of quality and affordability.
