Lately, we’ve had a lot of questions about exhaust systems, but more notably, DPFs.

The DPF or Diesel Particulate Filter acts as a part of exhaust system for the diesel-oriented vehicles to trap smoke (soot) and heavy particulates produced by the combustion of the engine. The DPF is very important component for manufacturers to maintain and meet the Euro emission standards which are becoming more stringent, although these filters have some drawbacks as well. The DPF block causes back pressure that can lead to decreased performance and increases in fuel consumption.


The DPF is considered to be “blocked” when the DPF of the vehicle becomes clogged with particulates or heavy particles, soot. The vehicle ECU often measures this by the amount of particulates in the DPF measured in grams. Once this value exceeds that of the value pre-determined by the manufacturer inside the maps of the ECU that control this, a MIL Code (Malfuntion Indicator Lamp) often dispalys as a result of this. often accompanied by and an orange DPF light displayed on the dashboard as a kind of warning that vehicle’s DPF is blocked.

“Deleting” the DPF

It is now quite common knowledge that when the DPF becomes blocked, it has a lot of disadvantages for certain vehicles, so a DPF Delete solution can be beneficial to overcome the drawbacks that vehicles can attain when this system fails. An increasing question from our clients who have been lead to this, is generally due to Facebook Forums. “Deleting” the DPF is possible, and involves altering and/or removing the DPF, and its functionality from your factory ECU.



This, by law, is permitted for off road use only, as tampering or removing Emissions Control Devices is not only illegal, but

ECU Remap with DPF still in place

With our professional ECU Remaps, we have achieved excellent performance improvements with vehicles such as late model Toyota Hilux, Ford Ranger, Nissan Navara NP300, with the DPF filter still in place.

With our experience and technology, we are able to achieve the same and/or very comparable results with your DPF FIlter still in place

We always recommend to retain your DPF for warranty and insurances and have a custom ECU remap which gives you:
