Going back to stock on my Focus ST

Hey everyone I was wondering if anybody could help with this I’m planning on selling or trading in my ST but I’m running a E-30 Tune by Alan at edge auto sport for the last year I only have the E-30 slot no 93 slot and i know a lot of people tend to stay away from cars that require a mix because E is hard to find. I’m trying find away to go back to stock tune or thinking about just getting a 93 tune from stratified and calling it a day. All recommendations are very appreciated.
