The diesels will really react to air flow improvements, bigger exhaust, and a chip... I've got a V-10 laying in the corner, someday going to build a light little car to put it in and see what happens....
Anyway, pulling around that much mass, a couple mpg improvement is probably about the best you could hope for... Changing all the lubes to synthetics would probably accomplish the same....
