Can i get a 92 octane tune?

[iLikeMustang]

hey fellas I live in WA and we don't have 93 out here, only 92, so I can only run the 91 octane tune is there any way for one of the techs to send me a custom 92 tune? maybe just tone down the 93 tune or something? I have a couple of mods also so if you guys could incorporate those into the tune I would really appreciate it

Use the 91 tune, you can try adding a little spark advance there.
