My experience with octane boosters is crap. I used to run a modified GSX and I tried different octane boosters, NOS was one of them, and not only did they not work, they left an orange colored deposit on my spark plugs (When I took the car to the track I would change plugs). I needed to use a wire brush to clean the stuff off. I don’t know if it was oxidation/rust or what. I stayed away from octane boosters and just bought race gas.
