I also run in Arizona.

Good food for thought here and I thank all. As far as the possibility of simply lugging the engine, would that create the dieseling noise I described (it sounds like scattershot pinging)? It does not seem to happen when I hard accelerate from say 3,000 rpm....

Also, by adding the Octane booster and/or dialing back the advance, which possibility will be tested for, pre-ignition or detonation?
