Truckstuning provides DPF DEF EGR VGT SCR deletions on trucks


DPF Deletion

The primary reason for DPF deletion is to increase the truck's performance by removing some of the restrictions put in place by the DPF system. The DPF system reduces the quantity of particulate matter (PM) and nitrogen oxides (NOx) emissions from trucks, which is great for the environment and human health. However, it also restricts the flow of exhaust gases, which can reduce engine power and fuel efficiency. Therefore, the removal of DPF can increase exhaust gas flow, engine power, and fuel efficiency, primarily benefiting truck owners that operate their vehicles in off-road, agricultural, or sporting environments.



DEF deletion on trucks happens when the diesel exhaust fluid (DEF) system is removed or altered. This system helps to reduce emissions by breaking down harmful pollutants in the exhaust gases. However, some truck owners choose to disable or delete the DEF system in order to modify their vehicles for better performance.

Deleting the DEF system involves removing the DEF tank, filler neck, sensors, and wiring harnesses. The purpose of this modification is to potentially increase engine power and fuel efficiency, as well as avoid spending money on purchasing DEF. However, this illegal modification can cause bigger problems for both the truck and the environment.


EGR Deletion

EGR deletion refers to the removal of the EGR system from a diesel-powered truck. The EGR system is responsible for recirculating exhaust gases, which can be detrimental to the engine over time, leading to a build-up of carbon deposits, corrosion, and other maintenance issues. Additionally, the EGR system siphons off some power from the engine, resulting in reduced fuel efficiency and less desirable performance characteristics.

For these reasons, some truck owners opt to delete the EGR system from their vehicle. The benefits of EGR deletion include a reduction in maintenance costs associated with the EGR system, as well as improved fuel economy, engine performance, and longevity. By removing the EGR system, the engine can operate at optimal efficiency, resulting in a better driving experience.


VGT deletion

There are several reasons why a truck owner may choose to delete the VGT. One of the primary reasons is to improve engine performance. With VGT deletion, the truck's engine is free to operate without restrictions from the turbocharger, resulting in improved horsepower and torque output. This can be especially beneficial for drivers who need extra power for hauling heavy loads or towing.

Another reason why a truck owner may consider VGT deletion is to improve fuel efficiency. While a VGT turbocharger can result in improved fuel economy under ideal conditions, it may not always perform optimally in real-world driving situations. By removing the VGT, the engine can operate more efficiently without the turbocharger's restrictions, resulting in improved fuel economy.
