Hey Mako.....exactly what kind of "mods" did you do?........I've got a F250sd 4X4 crew cab with the 7.3L and average about 15 to 16 around town.......18 to 20 (unloaded) on the highway.........Highest ever recorded was just over 20.
I have a DP tuner ,4" exaust, wicked wheel compressor turbine, kwik filter air filter NAPA part #6637, waistgate disable, 4" down pipe, high pressure oil crossover, brandnew Jasper trans,18K mod,TC lockup switch and a lite foot well at least sometimes.oh yeah I use diesel kleen in every tank, man that stuff works. I did not spend a lot of $$$ on extreme mods just wanted a good kick in the rear. most of these mods I read about in the PSD forums, but a lot of those guys are in it for kicka$$ power not milage. for about $5.00 you can try the 5.6K,10K, or 18K mod its a pretty good low end power boost,and at cruse you don't have to put as much effort into the pedal in my case that alone saved some fuel. hey man sorry so long I just love talking about my PSD!!!!
