Will it make a difference on the dyno if i use 108 unleaded octane?

Hey guys this might be a dumb question but i'm just curious so when I end up dynoing my car at some point, i was wondering if running 108 unleaded would make a difference over running 100 unleaded? And also if i got a custom tune from jordan tuned for race gas or 108 specifically (idk if he would make a tune for general race gas or for the actual 108), would that make a huge difference?

Let me know!
Thank you for your help!
