New Mexico doesn't have 93 octane; what to do?

[Lizard96]

b/c of the elevation level, we only have 91 octane. can i still use the 93octane setting on Predator?

would it be the same, since 91 is more powerful at higher elevations? or do i have to go with the 91 can tune?

Run the 91 tune and see if you have any knock retard. Just data log all the knock PID's.

I'd run the 93 and log for knock retard.

Arizona and California also only have 91 octane. Fortunately there's a 91 octane tune in the Predator so you are covered.

I have the u1734 and it only came with the 93 can tune. I just tweaked the timing and it works fine.
