U7191 C6 with 93 Octane

[quicktrip]

Running 2005 LS2, M6, VaraRam & Corsa Sport exhaust. Average altitude here is 4700 feet. Used 93 octane tune for track use with 93 octane available at facility. Will be traveling extensively back east where 93 octane is available, but many fill-ups will be at locations with only 91 octane available. If I keep the 93 octane tune in, will there be an issue using 91 octane where necessary? Altitudes will vary from sea level to 6000 feet.

There wont be any issues as if you have to run lower octane, the C6's knock system will pickup any sort of knock and adjust your timing accordingly. I would make an effort not to rag on it while you run the lower ocatne fuel though.

Thanks, Johan. Just wanted to be sure.
