gotta love it. NEW full size gas trucks average 15-16. cummins has had their stuff together for decades. Ill never buy another gas truck. My next one will be a 3rd gen common rail 6 speed. But ill wait a few years and let the prices come down, cuz mileage on a cummins doesn't make aMy 24V full ton dually gets me about 21-22 mpg hwy.

Unfortunately with the ppump, there's no real "fine tuning". But with the twins I wouldn't be surprised if your truck saw 16-17 mpg. What injectors do you have? I'm about to start setting mine up. Shooting for about 4-450 wheel hp.
Does that thing poor out smoke? Holy crap 11mpg sucks. What's the tuner set on?common rails do make some mad power with a chip! think i have a boost leak on mine, only get 11mpg and can only hit 29psi of boost, and i have bigger sticks, boost fooler/ chip, FASS, so i know im getting enough fuel? anyone else have any ideas?
. Damn, is it tuned, or tuned up to make big hp numbers? I'm thinking about taking my pump up to Jeff Garmon and letting him rebuild and tune my pump. You guys in the Cumminsforum?I actually have my AFC tuned pretty good. Burns pretty clean for a dinosaur. Just gotta spend tons of time adjusting preboost and the starwheel, along with changing springs with different spring rates on the AFC arm to change the fueling curve. Right now I'm running 7X.012 sac nozzles, but probably gonna step up to 5X.018. Right now I'm gettin about 13 mpg

Check turbo, routing. Intercooler and pull the turbo. Check end play in the shafts. Check airfilter to make sure it's not cloggedYep smokes a ton, always blowin black ha. And it's a quadzilla set on power level 3, gets don't get over 1200
