Oh yeah, you're in the right place.
The Minotaur software will come with a couple base files to get you started.
Basically anything that the PCM has control over (transmission included) is "tweakable" with the Minotaur package.
I've been using it for the better part of a year now and have been tuning 7.3s for almost two. If you're looking for tuning software for the 7.3L from some other company, don't waste your time or money...ask me how I know.
