Predator and Octane-300C

[TMag]

I just recently purchased a 2007 300C, also interested in purchasing a Predator Tuner for it. Question I have, I live in Texas, highest octane rating is 90. I see that the specific tuner that I need has 91 or higher. Is their a solution to this or would I just run 91 tune with 90 octane fuel?

You could use the 91 tune and log for knock, and adjust spark if necessary.

Thanks

I live in Lubbock, maybe its the station I use down the street, 90 octane is their highest. I will check around other stations.
