Canned tunes are the generic tunes provided with the tuners, one size fits all. They will be improved, but are not tailored to your individual car, or individual mods. You can also do email tunes with one of the expert MOPAR tuners, they have you log and send them info, they send you a tune, you log with that, and so on. Best generally, once you have your mods you are going to do, is a Dyno tune with a good tuner. They run it on the dynamometer and log and adjust until they get the most out of it (in theory at least).
So the generic (canned) tune that comes with the tuner, you just "install" the 93 octane tune (requires you to use 93 octane from then on). You'll get some improvement
Email tune gets better each revision until you arrive at what is considered an optimized tune based on the logs you provided (and depending on how many revisions you get)
Dyno tune usually done in one session, takes multiple dyno runs. Bonus is you get the dyno results so you can see pretty accurately what power you picked up with the tune
2015 + require either having the stock PCM unlocked, or buying an additional unlocked PCM. So with a 2013, you save the expense of the PCM
A Guy
2014 and earlier don't need the PCM unlocked, so you could get a tuner and run a 91 octane tune for instance and pick up some HP. Start a thread in the dedicated SXT forum if you like, and you'll get some suggestions. Beyond adding a supercharger, or turbo(s), there is no real cheap way to add much performance, but you can pick some up. You'd likely want to get a custom tune at that point to take advantage. If you get a tuner, make sure you take that in to consideration as some tuners you can only apply the canned tunes.
