Im aware of the reccomended octane raiting of 91 as listed on the gas cap. But in my area I have several gas stations that sell e93, 94, 96, and 98.

I just want to know which gas gives me the best power output without messing the engine up.

In Europe we have 95 and 100 octane, i mostly run it on 95 but also tried 100 and i really cant find a difference (my car is a usa import so its b46)

If the car isn’t tuned for the higher octane it doesn’t add any horsepower so if your still on factory tune then 93octane would be max horsepower.
