You can change from a paper factory filter to a K&N cleanable filter. The cleanable filters often pass air more when they are dirty than a clean stock paper filter.
Or can you add a different air intake. A diesel engine thrives on air and air out. Two of the best things you can do for a diesel engine is a new air intake and a 4 inch exhaust to reduce back pressure. I have gotten up to 23.8 mpg out of an F-350 with auto trans and a 7.3 l diesel.
