In a word, nope. You're good to go until you start getting into other mods.

its always best to run 91 octane or better, that is usually what the manufacturer recommends, it also will improve your performance and fuel economy

On a stock mm you will get the best performance unning 87 octane. premium is a waste of $$ on a stock sled & it will actually decrease performance. Owners manual actually says to run regular.

Yep, that's right. Higher octane fuel essentially burns colder and makes less power unless the engine was designed to run on it. Regular fuel is the right choice for a completely stock sled.
