More than likely it limped the trans. Bully Dog is a little rough around the edges with shifting in the allison.

What else happened? or was that it? did it not want to rev above 2,000 rpm or did it say in 3rd gear? or none of these? cause ones motor limp and the others trans limp. did it throw any codes?

Bully Dog has been known to give all the diesel companies issues, I hear nothing but nightmares from the powerstroke guys. Most of those guys get rid of the bully dog and get a SCT.
