Anyone have A 91 octane tune? expected power?

So as of 2 days ago, the only 93-94 octane places anywhere near me both went to 91 octane.... All my other vehicles are tuned for 93.... urgh. Sort of buying octane booster for every fill up, what kind of power are the 91 octane tunes making? Since now it looks like very few places in the City will have 93 anymore.....

Your barely going to notice the difference unless you put e50 in it

Considering a 93 tune can take them from high 13’s to mid 12’s....I’d say that’s more than “barely” noticeable. The difference between 91 and 93 won’t be much but starting from new either one is a huge jump in performance.
