I recently had a custom tune done and was wondering why the ABS and TC light won't go off. Is there an Update on the tune or program to correct the ABS light issue. I'm trying to get a DOT and they won't pass me with the light on.

I doubt it is the tune, I don't know what truck you own, other than it is a Paccar... How about a make, model, year... But, on my ProStar, it was a bad compass module that set those off on my dash. Compass module, as in North, South, East and West...

Try replacing the fuses too, they tarnish and will test good, but in reality they ain't. Another issue of the ProStar.

I'm not sure if I need another program to trouble shoot but I hooked cummins insite up and no fault codes.
