Should I only use 98ron with rstuner remap?

[xr2racer]

So obviously the .cal file actually has 98ron in the name but what does it mean.

Does the car perform slightly better on it because the map is optimised for it or does it need it to run properly? Am I going to be causing it to not run right because I'm using standard 95ron fuel?

Just means itll make the most efficient use of 98 iirc, if its been mapped to make use of 98. I dont think youll cause problems using 95.
