yes it can
Just some background info;
"hemifever" is a guy. His name is Sean and he's been tuning for quite some time. So a "hemifever" tune is just a custom tune written by Sean. He's what's know, as a CMR tuner (ChipMaster Revolution is the software they use for writing these tune files) There are other CMRs out there as well but most do default to Sean.
As far as the DS tuners themselves, they are a completely separate entity. The tuner comes with its own preloaded or "canned" tunes that are very conservative. But they also allow for custom tuning, so when your CMR writes custom tune file and emails it to you, you simply load it onto your device and then onto your truck much like any of the canned tunes. The trinity is the top dog as far as tuners go, the most capability and works across all years of our trucks. In 2011 chrysler changed the PCMs and the InTune wouldn't work with the new set up, so they created the DCX InTune specifically for 11+ chrysler vehicles. It's no different than the regular Intune tho
