Hey,

I have a 2012 Dodge Ram 2500 Cummins Truck, the gas mileage im finding is alot worse then my 2003 Dodge Ram 2500 Cummins.

Any ideas on getting better diesel mileage out of the truck? Modifications? maybe a chip?

With all the emmisions garbage on the newer diesels that can cut down on the milage because the engine has to work harder to breath and get rid of the gasses.

It's new... Very tight and solid. It WILL improve over time. Helping it to breath better will help too.

You have a DPF system that uses the fuel as a catalyst to burn soot particles, and you also have an EGR system. I would leave those systems alone because most states in the union are adopting some type of emissions laws. I would wait till after your warrantee has expired before you start tuning the vehicle. However; there are some warrantee friendly products to open up your intake.
