    2008 cummins CM2100 help

    CM2100
    OS 61300434AM
    I have this in a 2008 F-250 now and I am trying to tune it for the best fuel economy. Im not interested in violent power just reliability and fuel economy.
    There is something still on in the tune that is causing it to try to regen or something. it turns on the engine brake and loads up and gets ultra rich and burns a 1/4 tank of diesel in like 50 miles . I really dont know what to do from here I dont have any XDF files for it or anything to aid in helping turn things off. Also I know that the SOI timing can be adjusted to help fuel milage. Any help is greatly appreciated. 2008 Cummins CM2100.hpt
