Did you get pinging with the 92 so far ?
If you dont hear it when you're running hot n going up the hill on high gear, you will be ok
Knock sensor may be taking care of it....
12:1 on aluminum engines is not that high n if you are running 4:10s it helps take load of engine-Ferraris n Ducatis are pushing 13:1
Push comes to shove you can buy 100GT Unleaded fuel at your local drag strip or local distributor from Sunoco, VP Fuels, Unocal to name a few
Mix accordingly to stop the pinging
Also keep an eye on your spark plugs for what looks like pimples n broken porcelain : Signs of detonation....n black smoke under hard acceleration when piston rings gets rattled n lose sealing...
