Deleting the EGR and DPF from your truck is a simple process, and it is essential in reducing emissions such as the unburnt carbon and nitrogen oxide. But suppose you don’t wish to reduce emissions. In that case, you may consider increasing the mileage and the HP and, for example, increasing the HP to approximately 150 HP and mileage of approximately 5 MPG to increase the diesel engine’s performance.
The Duramax LMM is recommended for off-road only away from public places or roads due to the emissions such as carbon dioxide that pollute the environment. Each country, especially the US, has rules and regulations on operating such truck diesel engines and the most preferred places to avoid disturbing people in the surrounding. The article below describes how to delete and tune the DPF and the EGR systems from the Duramax engine.

Components of the Duramax LMM delete kit
1) Diesel particulate filter tuner
Before adding or removing any system in the Duramax LMM, ensure you have the required tuner that will enable you to carry out the whole process successfully. Tuners exist in many different forms depending on the manufacturers, and they perform many functions. Functions of the tuner include; monitors the amount of fuel being consumed, monitoring horsepower, and monitoring the towing modes.
Despite all the tuners performing the same functions, only a few tuners can unlock the truck for real power and the reliability of removing or adding the truck systems such as the diesel particulate filtrate and the exhaust gas recirculation system. Among all the delete kits, the Duramax LMM is the best since it can perform all functions above, including adding and deleting some parts such as the exhaust.

Installing the race tuner in Duramax diesel LMM 2007-2010
Installing the tuner in the Duramax LMM requires fewer tools, and the block-off system is usually switched on. To increase the model’s lifespan, it is essential to use a block-off kit to clean the diesel engine frequently. When deleting the emissions, such as unburnt carbon, remove and unplug all sensors from the wiring harness. Finally, seal all leaks present in the connectors to prevent the accumulation of dirt and water intrusion.
Most users prefer deleting theDPF filterand the CCR after successfully installing the tuner. The tuner brings the truck back to its correct functioning. Also, the EGR system is completely deleted during the installation with the shutting off of all the valves present.
2) Diesel particulate filtrate deletes the pipe
An exhaust pipe may be used in place of the filter. The pipe is usually positioned at the back of the downpipe back. It allows the truck driver to use the recommended tuner to remove the system permanently without any challenges.
The best DPF delete exhaust pipe
The pipe is commonly used in the Duramax LMM 2007-2010 6.6L. The exhaust pipe comes with many features that are shown below.

Annual mpg for Duramax LMM delete kit
The total mpg for the trucks varies depending on the model of the truck. For instance, a 2020 Chevy Silverado containing the 3.0l Duramax LMM has an mpg of approximately 33 when running on the high. When running in the city, it has an mpg of approximately 23 mpg.
Getting the best mpg that has a Duramax LMM
Economizing thefuelused for running your truck is easy instead of buying new diesel each time, increasing the fuel costs. It is possible to upgrade the Duramax engine truck to improve its performance and reduce fuel costs. There are several tips one can follow to get extra mpg for the truck. The tips include;
- Avoid leaving the truck idle for a long time, especially when not in use. Leaving the idle truck uses a lot of fuel, and the gas is wasted.
- Run the truck slows since driving faster results in the truck consuming a lot of fuel and avoiding being heavy on the fuel or the gas.
- Monitor the tire pressure, especially when running the truck. If the tire pressure falls below the recommended one, there is an increase in fuel usage, increasing the costs for refilling fuel.
- Ensure you service and maintain the Duramax frequently to prolong its lifespan. If the Duramax LMM parts fail to function, as usual, they result in a drop in fuel usage, especially if not examined and resolved immediately.
Frequently asked questions:
- How can I find my current mpg in my Duramax LMM?
Mpg in each truck with Duramax LMM vary depending on the rate at which it is running and its state. Most truck drivers wish to know the mpg present in their truck before increasing or reducing it to the desired level. The following steps describe how to check the current mpg.
1. First, locate the truck fill-ups and record both of them.
2. Allow fuel to flow into the main tank until it is complete.
3. Check the master odometer, and then read the mileage recorded after resetting the trip odometer.
4. Start the truck and run it for some time until the tank becomes at least half.
5. Repeat the refilling process but ensure the fuel does not overflow. Fill the fuel to the recommended level.
6. Again record the mileage measurements together with the fuel used to refill the tank.
7. Make recordings on the miles driven when the tank was full and after refilling the tank again.
8. Calculate the truck’s mpg by diving the miles driven by the amount of fuel used to refill the truck tank. For instance, if you recorded 150 miles and refilled the tank with 8.0 gallons of fuel, then the mpg is 18.75 mpg.
After getting the current mpg, you may use the following ways to increase the Duramax LMM mpg.
- Delete and tune the diesel engine truck.
- Using direct current and not AC.
- Removing the old fuel filter and installing a new one.
- Deleting the tailgate.
- Upgrading the truck components such as theair intake.
- Installing a bed cover to increase the mpg.
