Commifornia max octane rating is 91, less we forget (which I see SoCal in your location, so you should be well aware lol)  |
I just re-read OP's post, he's on 100 RON which is like our 93.. But if the car was tuned for his old setup on 100 RON then that's where the issue lies.
OP I'd ask your tuner how balls to the wall he went on the last map, if he left some on the table you should be fine, but if he was on the edge of knock trying to squeeze every last hp out of the car then you might have an issue.
