It seems many folks run a higher octane than their tune is designed for just for extra insurance which I completely agree with but what if you have a 93 tune and want that extra insurance. Do octane boosters really raise the fuels octane or are they snake oil? I was considering some Amsoil octane booster as they have a pretty decent reputation in the oil world. What do y'all think about the octane booster concept in general? Thanks!
