I just switched from a 2003, to a 2007 Dodge Ram 6.7l. I am taking it to central America, where I know there is no low sulfur diesel (much less ultra low). What modifications do I need to make, to keep it running on good ole regular diesel? I read about DPF/EGR deletes, and several other ways to make improvements to the MPG, but what to do in this case? I'm going to be using it for hauling cattle on mostly winding roads, probably never getting over 45 mph. Any ideas?

 

The DPF and EGR deletes for sure. Will the 6.7 injection system safely run regular sulfur fuel? Im not sure on this matter.
