My cummins is getting 15mpg and that was with me babying it seeing just how good milage it could get. somethings obviously not right i hear of cummins getting the lower twentys in mpg from MANY dodge owners. So ive been told S&B Cold Air intake can increase milage.

 

lots of things can increase mileage, intake filter, intake manifold( big restriction), box that adds timing

getting 20+ mpg is for those with long highway drives staying around 2000RPM.
