I finally got my JLTCAI for my 07 Mustang GT, hooked it up, plugged my predator tuner in and was excited and ready to go except for one thing! thePredatortune for the JTL CAIonly has a setting for 91 octane, ok fine, so i get in my car drive to the gas station and realize they only have 87,89 or 93 octane at the BP i then drive to Mobile,Exxon,Shell,ect. with negative results on the octane hunt. I live in New York City and was wondering since im a rookie to the mods thing where can i get this fuel or do i have to now get a custom tune for JTL and another octane?

Where did you get your tuner from? Did you just buy one tune file? Just fill with 93 octane and run your 91 tune. Everything will be okay. You could mix in a little 89 with the 93, but I wouldn't mess with that. just go with the 93. Not worth ordering an extra tune for the cash.
