I know people that have a JB4 can benefit from higher octane. but on a stock engine, would you get better overall engine performance if you add some octane booster when you fill up? most pumped around me are 91 octane.

Unless the engine is designed to use the higher octane you won't see any benefit. Doubt it would do any harm to try it.

The benefit also depends on your driving habits. You can add 500 HP but it won't do you any good if you are in heavy traffic creeping along at 25 mph. If you insist on being first away at every light, maybe it would help.
