the higher the octane...definitely safer in regards to knock...
commanded AFR vs actual AFR will change between different octanes and the motor will usually make more power at a higher AFR with a higher octane...
you can definitely run higher spark levels w/ a higher octane as well...
whether any of this is noticeable between 89 & 93...???...I dunno...I doubt it...
I'm referring more to the difference between 93 and say, 110...
where are you N. of ATL? I assume near the Anheuser-Busch brewery...?

Yes on the AFR (PLX) on the pillar.
Well I had my tune flashed for Transmission tweaks only. On the way home I get horrible rattling. I call and the tuner is gone but I'm told it's normal after a flash for a relearn to happen. I was also asked if perhaps I had made a mistake at the pump.
Well 5 days later the ping is all but gone now and my AFR's are still @ 10.5 when they used to be 11.1 or 11.2 under WOT. I let the current tank get to 1/4 and filled up with 93. Who knows I may have not pressed the button enough, BUT I Doubt It!. I have had the blower on for near 5 years now.
What gets me on the relearn thing, the trans is on a different CM isn't it. And how come after the Dyno tune flash I had no relearn woes?
What do you think?
