There should be a Stock setting coming available from Smarty within a week or so. Then you can see what your mileage is with your foot not tuning involved. Just deletes.

what size tires do you have and if you are running 35s that put me off about 8-9 percent. Have u adjusted the ABS if you have bigger tires??

well, i personally have a hard time believing 22+mpg on any of these trucks. maybe downhill with a tailwind. the best i've seen is close to 20mpg highway, unloaded. i have a megacab dually 4x4 with the G56 and 3.73 gears, which runs just like the 4.10 in the auto. what tranny do you have? rear end gearing? 2wd or 4wd? cab configuration? and what flash?

That is definitely low there 101, especially with stock tires. What are you running your smarty at?

I would say you are a little low, but not too bad. I have seen as high as 17.8 1x but my running average is 15.6 so far @ 34,000 miles. all of this is hand calc'd and I did find my speedo was off a little from the factory. I reset it with the smarty about 16,000 miles ago. What kind of tire pressure are you running? On my old 2500 I ran about 75 in the front and 60-65 rear. How about the map sensor? some have had good results with cleaning the soot out of it. I've only run the smarty on 1,3 and 5 so far with default timing. I haven't noticed any real mileage difference between any of those levels. just a few ideas, jeff.
