Whether or not you have to run race gas is determined by a few things: compression, timing and altitude. If your sled is stock than your compression is fairly low (compared to race motors) and your timing is not advanced (where as race motors typically have advanced timing). Raising the compression and advancing the timing both would require more octane (race fuel). Because your sled is stock, you should be fine with pump gas as long as you ride above 5000 ft elevation.

You should not have to run any race gas in CO bur some guys throw a gallon or so in just for added safety. The altitude here is so high that your usually safe with out any race gas.
