    Default 2014 6.7 not responding to changes

    I have a 2014 cab/chassis 3500 here that I deleted and tuned. It is very weak and no matter what adjustments i make to the fuel and timing table it's makes no difference in the truck.
    I have the tune posted below, maybe someone has an idea. I don't have the scan file here with me.
    thanks, Lee

    So I'm assuming you deleted all hard parts. What did you do in the tune?
    (And now I'm not smart enough to look and see if it right)

    But I sense you are in some kind of a de rate mode and I think a scan will show that

    I couldn’t see where any torque management was pulling fuel. It is very weak till third gear then it seems to come alive pretty good. I am assuming it is done trans TM but I can’t find where it is

    I tried that file and it errored and said checksum failed. I have worked on this for a bit now and it has stumped me.
