440sp is on a distinguished road

I have a heavy 2500 (8800) 5.9 and 4.10 gears and I have done everything mentioned here K&N filter, open exhaust with shorty headers still have cat though, changed the front from hub bearings to lock outs which helped some but not much at least I do not have to change hub bearings anymore, no cam change though BUT the biggest thing that did help was I installed a vacuum gauge and watch it constantly trying to keep the vacuum as high as possible by doing this I went from 9mpg to almost 13mpg!! big jump considering it costs $$$$ to fill her up. As mentioned earlier these trucks are not fuel misers but pretty thirsty but again I have a heavy 2500 with 4.10 gears if I went to 3.55s I probably would see more MPGs but lose in the low end...hope this gives you some ideas.........
