You would probably get more carbon buildup running lower than 91-93. Plus if you have mods 91-93 is called for.

Depends on what your compression is... if you have compression highering components on the bike, like timing plates, port work, smaller domes/milled head, your into the race gas scene. If just bolt on mods, stock, etc... pump 92-93 and no lower.
