It depends on your mods.
The NOS MMT Octane boost will get you to 94/95 octane. The Torco Mach 1 MMT (32 oz. bottle) to 1 full tank of 93 octane will get you to 100 octane rating.
you can do a blend of 93 octane and e85 (E85 is an abbreviation for an ethanol fuel blend of up to 85% denatured ethanol fuel and gasoline or other hydrocarbon by volume) which will yield similar results as the TORCO additive for less $$.
Bear in mind that the 93/e85 blend is mainly intended to work in conjunction with Methanol injection and the Jb4 Stage 2 tune. IF you do not have this, you will need to wait for the BMS e85 wiring bundle. (Per Terry @ BMS)
That being said, depending on your configuration, you will need to do the MMT additive (NOS MMT or TORCO MMT) or the 93/e85 blend 50/50 or 70/30 respectively.
Pick your poison.
