Some diesel owners are opting to “delete” these pollution-control components instead.Ī diesel delete involves taking out the DEF system, removing the catalytic converter and DPF, and installing a new exhaust. ![]() The vehicle’s ECU (engine control unit) will also have to be reprogrammed using a tuner. This tuner will replace the OEM (original equipment manufacturer) software with a new program that controls the fuel delivery and engine timing. The tuner will also recalibrate the OBD (onboard diagnostic system) to properly monitor engine operating parameters and ensure that no emissions-related codes pop up because of the missing components.Īfter a diesel delete is completed, the soot-clogging issues are eliminated. There may also be performance improvements such as an increase in torque/horsepower as well as an improvement in fuel economy. These positive changes can depend on the tuner, the after-market software, and the engine hardware. There are three types of kits available when it comes to performing a diesel delete: DPF, DEF, and EGR. These diesel engine services are popular among diesel owners. The DPF (diesel particulate filter) is a component build into a diesel engine to help remove soot from the engine. This soot is then stored in a canister that contains honeycomb-shaped compartments. Once these honeycomb components get clogged up, the exhaust becomes restricted and starts what is known as a “regen cycle”. This cycle involves using diesel fuel to burn off the soot to push it out of your exhaust system all at once. If your DPF becomes damaged, it can be quite expensive to repair. Plus, removing the particulate matter can affect your vehicle’s power, fuel economy, and engine life. Over time, an existing DPF system will create poor fuel economy. Once removed, fuel economy can improve by up to 30%.īecause many diesel owners use their trucks for towing or carrying heavy loads, increased performance and power are a priority. The DEF (diesel engine fluid) system operates similarly to the DPF, removing soot from your engine and storing it in a canister within your exhaust system.įor this reason, many diesel truck owners opt to have a DPF delete done on their vehicles. ![]() Just like the DPF, the system will clear out excess soot by going into a regen cycle and using your vehicle’s fuel to burn off and blow out the soot. The DEF can also reduce performance and fuel efficiency but can also cause issues with the system freezing up. DEF is mostly made of water so, when you live in a colder climate, you run the risk of having your fuel freeze within the DEF system. The EGR (exhaust gas recirculation) system reduces your diesel vehicle’s exhaust emissions. An electronically controlled valve allows small amounts of vehicle exhaust to mix with the air intake stream to reduce the nitrogen oxide exhaust emissions. While it limits the amount of exhaust released into the atmosphere, it also increases the amount of soot in your engine and reduces performance and fuel economy. EGR systems can also cause engine troubles such as cracked parts and other expensive issues. It can also create other issues such as sticky valves, leaky cylinders, cracked engine components, and coolant problems.

The truck will run properly but you will still have a check engine light and DTC. *2015/2016 Ford – Some trucks may set a crank case ventilation sensor code. Larger tires and poor driving habits will reduce mileage. After installing theH&S Mini Maxx and deleting the DPF/CAT expect to get a combined mileage of 18-19 mpg. More or less depending on the severity of the restriction. If your DPF is plugged up your probably averaging 13-14 mpg. The H&S Mini Maxx includes DPF present and DPF removed tuning.Įliminate the following components (if equipped) without setting any diagnostic trouble codes or check engine light:įuel Mileage –Expect to see significant fuel mileage gains.
