Yes, but the box tuning leaves a lot to be desired.

I made it from 30xxx to 70xxx with the box tunes.
I am running almost exclusively in the +200hp file when not towing.
I saw up to 20mpg on 35’s with 68RFE.
The truck never really ran right, like a gasser with a dropped cylinder, except for some specific scenarios where the converter was locked, in 5th or 6th gear, and pulling from about 1500-2100rpm.
No trans issues to speak of.
Did have issues building too much boost on box files.
I went to DRD tunes, and now the truck runs like a Cummins should.
It didn’t strike me as not running right until compared to a common rail 5.9L or a 12V P7100 with a 4K spring, HX40, that has seen a flathead and has bigger injectors which ram WAY better than my 6.7L with box tunes.
Now am seeing a 22-24mpg average in a higher hp setting.
