I got 16 mpg wilth 2 4x4 5 speed duallys with the edge with attitude,(4.10) pipe, aftermarket air cleaner, one was a 98 5.9 and other was a 2001, wife has a 3.54 2 wd automatic and gets about 18 in her dually with edge pipe same extras. My 6.7 4x4 (3.73) with complete delete and Smarty 67 ME gets about 20mpg. its single rear wheel and 6 speed manual and 5 inch pipe. The 6.7 is a good truck after u delete it and update the clutch, 120k and no injectors so far, runs better than new after the egf pdf delete. The clutch needs to be updated to the Southbend one about $1500 and I am nursing it another 10k miles. If i turn up the Smarty beyond 30 hp it will slip, the dual mass is a junk set up and no good, its gone out beofre on me with stock motor. The 5.9 i had all had the usouthbend update and no clutch prob after that install and 200k miles, also updated the input shaft on the nv4500 t the same time and the hydra slave cylinder, those southbend clutches are hell on pedal presure increases, they have the hyda update in mos clutch updates now sold, back then thye did not tell u if will kill your leg in San Antone or Usston Texksus traffic!!!lol
