Yes, you can use 93 with the 91 tune. Superchips tends to run a little more timing and you may even get a little (not harmful) Knock Retard with 93 in the tank. As far as setting the tranny up, if you don't have a good understanding of what's going on, you're smart not to mess with it. IMO, what you should do is make notes on what you don't like (shift schedules, torque management) the way it is set up stock, and make notes on how you would like it to be. Then you should graph the stock settings, as read off the Superchips App., and next graph the settings the way you want them to be. On mine, the vertical leg shows throttle position in %ages in 10% increments. The horizontal one shows miles per hour in 5 mph increments. Once graphed, you should be able to get a good idea of what is going on. Just do not overlap the up and down shifts for the same gear and you'll be good. Also, the closer the up and down shift graphed lines are to each other, the more sensitive down shifts will be to throttle opening. As an example, my second and third up/down lines are pretty close together, so when I am putting around town, it only takes a very slight application of throttle to make it downshift. This livens it up and never lugs the engine. In other words, it's set to keep the RPM higher, rather than lower. One other thing, using another person's setup may not be suitable for you, as the way you want it may not be the way the other guy has it, and it may be worse for you than stock. For instance, I have mine set up to take maximum advantage of the aftermarket cam I have installed in mine, and also to maximize the Hemi MDS "on" time. I have it set so it doesn't up shift from 4 to 5 until about 70 mph. This allows me to run in 4th gear on the highway (closer to the cam's power range), and keeps the MDS on at least 90+% of the time. Hence, 20-22 mpg, with a high of 24 mpg. Finally, once you graph everything and start tinkering with it, I am sure you'll pick up on it. I've had it on mine since the App. came out, and I still, from time to time, tweak some of the settings to suit my desires at the time. If you really get stumped, let me know, but give it the good old college try first.
Edit: If you want to just mess around a little with the stock shift schedules, just start tinkering with the light and wide open throttle torque management settings for each gear. It's pretty hard to determine how to set it......just trial and error until you're happy. I lowered each of the setting by about 10-15% at a time until I got it where I wanted it. Just be aware, that with in the lowrer gears (more gear reduction), 10-15% may make quite a difference in shift firmness. As you get to the higher gears, you may end up with half or less the stock settings.....that is if you want firm shifts and not the "soggy" stock ones.
