That depends on who created the tune for you. Usually they tune for 93 octane(91 in CA) unless you specify otherwise. Who did you get the tune from?

I do not have one for my stang yet, but the tuner for my F150 had the option when you first started the tune. It asks you what you wanted to install. I just changed my back to 87 yesterday because I am going out of town.

Yeah i got my tuner from mustang tuning.com and it just has options for diable tune (which is the 93 tune) i believe, and factory back up.

for us you only have the option to load the diablo tune (93), or modify your factory tune to suit your needs, the 3 tune option predators are only for the 05+ stangsm, I contacted diablosprt about this, I bumped my timing up 3%, did a bunch of other stuff, but I run 87 with no problems, but be carefull adjusting your timing unless your running 93

dont' mean to hijack but can you feel an off the line difference when running a tuner?

good question. i guess if your stang is stock, its only like adding 5 hp to your engine. now if you have intake, exhaust, pullies, you know minor bolt ons and such, it adds ten. if you want to get technical, the tuner is "generic" and fits the "typical" fixed up mustang, which means you have minor bolt ons. now if you decide to take this tuner all the way, you get on the dyno and a technician punches in your specifics ( C&L intake, flowmasters, etc.) and that should add a sufficient amount of extra power. its all about exact info to get the most out of the predator.
