You can probably find some 93 or 94 if you look hard - if not, you may have to use octane booster. The other option that would be more permanent for you would be water injection (doesn't have to be meth). Or you could go further and do dual-pass, H/E, and meth or water injection. Those will lower your air temps and should eliminate knocking even at 91 octane.

when i picked up my car it was making a wierd ass noise too.. i left it running and called the manager over and he was like can i help you? i told him to listen and he said damn that sounds like ass. i said yea it wasnt making that noise when i brought it to you. so he had the head installer take it to the back and he routed some hose wrong that was supposed to be routed another way. it was rubbing on the transmission or somethng he said, but i think he was full of ****. i stayed for an hour after they had my car for 2 weeks, bitching them out.
