Most importantly, the Vortech tune falls under their CARB Approval certification, so if that's important to you, then you want the Vortech tune.
Beyond that, even tunes from the same tuner are going to vary from one to another, so if you're looking for specifics like that, you will need to reach out to both tuners, let them know the specific version of the tune you have, and ask them for the details so you can do a side by side. That being said, you may want to approach them with a more specific question rather than "could you tell me what you changed from stock?" as it could be a pretty lengthy discussion.
Perhaps a better question is, what are you trying to discern between the two? Are you making a buying decision between getting the full Vortech kit which includes the Vortech tune versus the Tuner kit from Perrin?
