does the 89 help to light up the tires faster so you can get rid of those worthless rubbers? :)

I don't know about you, but even stock tune with my 35's I could lite up the rear tires even with my 3.73 gears.

No lighting up tires. Got rid of those pieces of junk already. I'm still babying my m/ts

Since I live at moderate altitude, octane is different than sea level. 85, 87/88, 91 here.

Empty, lowest octane is fine. Towing, mid-grade is better - I have noticed a difference for sure. Haven't used highest octane fuel yet.
