What is the DPF and is it worth doing a DPF Delete?
The Diesel Particulate Filter (DPF) is an essential component in most post-2007 diesel vehicles, designed to reduce emissions. However, this device comes with certain disadvantages, including frequent maintenance and potential repair costs.
As the DPF becomes clogged, it increases exhaust backpressure, which disrupts fuel flow, slowing it down considerably. By removing the DPF, fuel can flow more freely and efficiently, leading to significant improvements in fuel economy.
Key Features
- Improved Fuel Efficiency: If your DPF is clogged, your fuel economy may be around 13-14 mpg. After performing a DPF delete, your combined fuel mileage could increase to 18-19 mpg, thanks to better exhaust flow.
- Eliminates DPF Maintenance: A DPF delete eliminates the need for regular DPF cleaning or replacement, saving you time and money on ongoing maintenance.
- Prevents Costly Diesel Repairs: By removing the DPF, you reduce the risk of DPF failure, which can lead to expensive repairs.
- Enhanced Engine Performance: Reduced exhaust backpressure increases exhaust flow, resulting in improved engine performance. When paired with an ECU remap, a DPF delete using parts can significantly boost power and torque, enhancing your vehicle’s overall performance.
Choosing a DPF delete with not only improves fuel efficiency and reduces maintenance costs but also optimizes your vehicle's performance for a smoother and more powerful ride.

Installation
Installation Process:
Installing a DPF delete kit from typically takes about 1 hour with basic hand tools. This can be done in your driveway or garage, and the installation process is faster with an automotive lift. Some cutting may be necessary for certain vehicle configurations, such as shorter wheelbase trucks. The kit comes complete with clamps, hangers, and hardware, though you may need to reuse some factory components.
Tuning Requirements:
To remove the DPF, Catalytic Converter (CAT), Selective Catalytic Reduction (SCR), or Diesel Oxidation Catalyst (DOC), you must also remove emission-related sensors. To prevent check engine lights or diagnostic trouble codes, you will need a DPF delete-compatible tuner, which provides as part of their high-performance tuning solutions.

Frequently Asked Questions
What is a delete tuner?
A delete tuner is a device that reprograms yourtruck's ECM (computer) to turn off emissionssystems like the DPF, EGR, and DEF, allowing yourtruck to run without those components
Can l use a delete tuner withoutphysically removing TheDPF/DEF/EGR parts?
You MUST remove your DPF(Diesel ParticulateFilter), as the filter will clog and stop all exhaust flowwhen shut off. You will no longer need DEF(DieselExhaust Fluid), and you may remove your DEF tankif you wish, or it can sit empty. The EGR may remainas is, but we recommend removing the physicalparts as well.
Is a Delete Tune bad for mytruck's engine?
Quite the opposite. In fact, many customers reportimproved engine life, smoother shifting, and betterfuel economy (typically 3-5 MPG gains) when usinga quality delete tuner.
What's the difference between adelete tuner and a delete tune?
The tuner is the hardware device. The tune is thesoftware file that gets uploaded to your truck's ECM.Your delete tuner includes a delete tune when youpurchase from us.
Do delete tuners void my warranty?
Yes. Any emissions-related modification, includingtuning, can void the manufacturer's warranty. Manycustomers wait until after their warranty expiresbefore deleting.
Do l need a mechanic to install thetuner? How long does installationtake?
Not necessarily. Many of our customers install their delete tuner themselves in under 30 minutes. We include easy-to-follow instructions, and our support team is available if you need help.
Will my truck pass inspection oremissions testing with a deletetuner?
No. Delete tuners disable emissions systems, so your truck will not pass emissions tests in areas where they're required. Some states have exemptions (e.g. heavy-duty or rural-use trucks).
Can l go back to stock afterinstalling a delete tuner?
Yes. However, in most cases you will have to have the ECM flashed at the dealership. If this is a concern, contact our team and we can explain further.
Is the delete tune VlN-locked?
Yes. All delete tunes are VIN specific and will only work on one truck. The tuner (hardware device), may be used on multiple vehicles for diagnostic or monitoring purposes where applicable.
