So, I have 2013 Pete with isx cummins, i had it mandaded for past 3 years now, and replaced 2 heads, one was faulty from cummins didnt last me a year, warranty covered that, got a replacement, was running great 170k after had to replace all the valves..

so im here to ask recommendation where I can get my a safe mandated tune, maybe dyno tune?

I get great MPG, 7+ loaded 8-9 empty.

depending on who and how well or -- more likely poor.. the head replacement and other mechanical work was done, you may not be anywhere near out of the woods with that thing even if you do get the programming fixed. - Those ISX engines have to be build 100% the right ways or they do not last for s$it,... and it is getting harder and harder to find any shops willing to take all the extra steps to ensure it gets done right.
