Use the 91 tune. Thats why they include it, for those people who can't get 93.

Gas is a matter of personal preference. Personally, I'd never put Chevron, 76 or any of that other stuff anywhere near my car. It lives on Exxon, Mobil or BP/Amoco.

I think Diablo recommend Mobil (read it somewhere I think).

What if you're like me can't get Mobil that means i don't get the true effect i should get with the Predator just asking

These are the brands that Johan recommends as well.
