Want to add about 150HP and get an average of 5 MPG more in fuel mileage out of your LMM Duramax?
If emissions aren’t a concern for you, then adding the HP and mileage is as simple as deleting the DPF and EGR from your truck. Be aware that these modifications are only for off-road trucks in the US, or for countries without these regulations.
Removing these highly restrictive and failure-prone systems allows your truck to breath much easier and run much more efficiently.
Below I’ve compiled the list of required parts that you will need to delete the DPF and EGR systems on your LMM Duramax engine, as found in the 2007-2010 GMC/Chevy diesel trucks.
DPF Delete Tuner
When adding performance or deleting systems on your LMM, the first thing that you’re going to need is a good tuner.
There are a lot of tuners that can help with different tunes for fuel consumption, horsepower and towing modes, but there are only a couple options for race tuners that are able to unlock your truck for the real power and reliability of deleting the DPF/DOC and EGR.
This is the best option for the LMM Duramax for a truly out-of -the-box delete capable tuner:
