Turbo Nytro at 10 pounds octane questions

[arctic cat 4 life]

Riding at 3000-6000ft is 100 octane race fuel okay? is 114 av gas okay? Is to much ocatne going to hurt?
And also, riding 5000-8000 same question. Any help would be awesome.
Thanks

if it has a shim 91 oct is lots & yes to much oct will decrease your hp & can cause other probs over time.
