hello.... octane
im upset to see everyone talking about afr's and no one is talking about fuel octane... when i was tuning a 91 fc with a ported cosmo, i went all the way down to 9.0 afr under heavy load 6k or so, 10 psi, and still got detonation, but this was with good old Cali 91 octane. iu put some 104 in the tank to dilute the cali crap and leaned it out to 11.0 with no problems... so remember, having a low afr # dosent mean its safe, just means its rich, wich means not all the fuel is burning, not that your car isint going to detonate or ping....
