So many truck owners look into doing a DPF delete on their Cummins ISX15.

Depending on personal priorities and the intended use of the vehicle, the decision to perform a DPF delete can vary. Some may prioritize improved horsepower and torque, while others may focus on reduced maintenance issues and better exhaust flow.

In this guide we’ll go over the ins and outs of a Cummins ISX15 DPF delete, the benefits, the process and things to consider if you’re thinking of doing this.

What is a Cummins ISX15 DPF Delete?

A Cummins ISX15 DPF delete is the process of removing the diesel particulate filter from the exhaust system of a Cummins ISX15 engine. The DPF, when installed, is designed to capture and store soot produced by the engine, reducing emissions. But over time these filters get clogged and decrease engine performance, fuel efficiency and increase maintenance costs.

By removing the DPF along with the associated systems like EGR (Exhaust Gas Recirculation)DEF (Diesel Exhaust Fluid) you can get your engine back to its power, improve fuel economy and reduce repair costs. Additionally, removing these systems can improve airflow into the engine’s intake, resulting in better fuel combustion, increased horsepower, torque, and overall efficiency.

Benefits of a DPF Delete for Your Cummins ISX15

A Cummins ISX15 DPF delete has many benefits especially for those who encounter performance issues or need to reduce operational costs:

Improved Fuel Efficiency The DPF system forces the engine to work harder to expel exhaust gases, thus lowering fuel efficiency. Once the DPF is removed, many drivers report noticeable improvement in miles per gallon (MPG). This translates to big savings over time, especially for commercial operators running long routes. Removing the DPF can also improve performance by enhancing horsepower and fuel economy, ensuring that your vehicle runs more efficiently.

Restored Engine Power The ISX15 is a powerful engine, but emissions systems like the DPF can restrict airflow and reduce its power output. Deleting the DPF allows the engine to breathe easier and often restores lost power and improves throttle response. Additionally, removing the DPF can improve turbocharger efficiency, resulting in significant gains in horsepower and torque due to reduced back pressure, which directly benefits turbo performance. This, in turn, contributes to better fuel economy.

Lower Maintenance Costs Maintaining a DPF system can be costly. Frequent regenerations, sensor replacements, and cleanings are common, and when the DPF fails entirely, it can cost thousands of dollars to replace. A DPF delete eliminates these ongoing expenses and provides a long-term solution to these problems, further enhancing the vehicle’s fuel economy by reducing the need for costly repairs.

Reduced Downtime For businesses that rely on the Cummins ISX15 for logistics, downtime is costly. When a DPF system fails or clogs, it can take your truck off the road for days and cost you revenue. With a DPF delete, the engine is simplified, and there’s less that can go wrong, allowing your vehicle to run longer without interruption, ultimately improving fuel economy by keeping your truck running efficiently.

In my experience working with clients, many operators have noted that their trucks run smoother after a delete with fewer unexpected breakdowns and lower overall maintenance.

Delete Kit Features

A typical DPF delete kit includes a DPF delete pipe, a tuner, and other components designed to work together to improve engine performance. The delete pipe replaces the stock DPF, allowing for increased exhaust flow and reduced backpressure. The tuner is used to reprogram the engine’s computer, ensuring that the engine runs smoothly and efficiently without the DPF.

Some delete kits may also include additional features, such as a universal pyrometer (EGT sensor) and docking station, to help monitor and optimize engine performance. These components work in harmony to ensure that your engine operates at its peak, providing the power and efficiency that Cummins engines are known for.

The Process of a Cummins ISX15 DPF Delete

A DPF delete on a Cummins ISX15 involves the following steps:

Software Tuning

First the truck’s engine control unit (ECU) must be reprogrammed to tell the engine to stop looking for emissions related data from the DPF system. This tuning is critical as simply removing the DPF without tuning will cause error codes and limit the vehicle’s performance.

Remote tuning services like the ones I provide using TeamViewer or AnyDesk allow this process to be done quickly and efficiently from anywhere. You don’t even need to leave your home or office. Once the connection is established the technician can access the ECU and do the necessary changes. This method is not only convenient but proven to work for hundreds of customers.

Physical Removal of the DPF

The next step is to physically remove the DPF from the exhaust system. Some opt for a complete exhaust system replacement while others may simply delete the DPF section and replace it with a straight pipe. It is also necessary to block off the EGR gas flow to prevent any issues.

EGR and DEF Delete (Optional)

Many truck owners also choose to delete the EGR and DEF systems. The EGR system recirculates exhaust gases back into the engine which can lead to carbon build up and reduced engine life. After the EGR has been deleted, the EGR gas flow must be blocked off with steel plates to prevent leakage of exhaust gases back into the intake. Deleting the EGR ensures cleaner engine operation and removing the DEF system eliminates the need for DEF fluid refills and further reduces operating costs.

EGR and SCR Delete

In addition to DPF delete tuning, some engines may also benefit from EGR (Exhaust Gas Recirculation) and SCR (Selective Catalytic Reduction) delete. EGR delete involves disabling the EGR system, which can improve engine performance and reduce emissions. SCR delete involves disabling the SCR system, which can reduce the need for diesel exhaust fluid (DEF) and improve fuel efficiency.

However, it’s essential to note that EGR and SCR delete may not be compliant with emissions regulations in all areas and should only be used for off-road applications. These modifications can further enhance the performance of your engine by reducing the complexity and potential failure points within the emissions systems.

Is a Cummins ISX15 DPF Delete Legal?

It’s important to note that while a DPF delete offers many benefits it may not be legal in all areas. Emissions standards in the US and other countries require vehicles to meet certain environmental guidelines and tampering with or removing emissions controls like the DPF, EGR or DEF systems may result in fines or penalties. Additionally, performing a DPF delete can be bad for the environment and may lead to legal complications and potential engine damage if not done correctly.

For off road vehicles or trucks used in racing or non-road situations a DPF delete may be legal. But for commercial trucks on public roads a DPF delete may be illegal. Check your local regulations before considering a DPF delete, as it can void the vehicle’s warranty. Tampering with the vehicle’s original systems not only leads to potential legal repercussions but also affects the resale value, as buyers may be wary of purchasing modified vehicles.

Off-Road Use Considerations
