Okay, yes that sounds like a dumb question since the 350 is rated for 526 on 93 octane BUT...the tunes do exist from VMP and there are California peeps on here too. I travel back and forth between 93 and 91 areas. So, anyone on one or have talked to a tuner about if there is anything to be had on a 91 tune?
