stands for diesel filter particulate, it’s telling of the fact that it is actually a filter that is installed within the exhaust system, with the prime purpose of filtering particulate and soot from engine exhaust.
The DPF delete, therefore removes or deletes this filter (DPF), so that the vehicle functions without it by configuration of the computer system.
The exhaust will be the one used to replace the DPF physically, and the tuner is responsible for disabling the regeneration mode of the vehicle and makes sure that no other engine codes occur.
Is DPF Delete Good?
Ultimately, the benefits of not deleting Duramax outweigh the costs of deleting it. For starters, deleting the Duramax can lead to huge legal fines if caught without it by authorities.
Furthermore if you actually wish to sell the vehicle, it would ultimately reduce its resale value because of the missing DPF. Deleting the filter can be very bad for the environment as well due to carbonated exhaust fumes.
However, on the upside, deleting the Duramax can lead to a more efficient and reliable turbo, increased power gain of up to a 100horsepower, as well as eliminated need for DEF fuel which will make the pockets happy.
Duramax DPF Delete Problems
For starters, deleting a DPF can cause serious air pollution to the atmosphere which thereby harms
the environment. To top it off, deleting the DPF is actually illegal and you may face heavy fines from
the authorities, and a lot of car servicing workshops are refusing to deal with deleted Duramax’ as

DPF removal affects insurance. This is due to the fact that the modification of removal the filter is actually very illegal as it goes against environmental laws and regulations put in place by the government.
This therefore puts the insurance company at risk of legal litigation as it has maintained an illegal contractual relationship with the truck that has had its DPF removed.
The insurance company will thereby want to avoid any bad publicity or litigation by any means possible and so they cancel the contractual agreement with the truck driver and the truck itself.
Does DPF Delete Increase Horsepower?
A DPF delete undoubtedly increases horsepower! It does this so much so that the power gains can actually reach up to 100+ horsepower which is perfect for those seeking significant improvements in horsepower. Despite high horsepower gains, other benefits are mostly reliability-related and include a more efficient and reliable turbo.
In conclusion, DPF removal can lead to increased horsepower gains, more efficient fuel use and decreased DPF fuel cost, however legal fines actually outweigh the small costs of having to service the car and suffice DPF fuel.
A truck driver is better off keeping the DPF than removing/deleting it as the costs are just too significant compared to the benefits. However, to each their own and in some countries, emissions legislation isn’t that tight and it’d be easier to get away with DPF removal without ever getting fined. This is very rare, but it happens. There’s nothing new under the sun anyway.
