I have tried many different combos. I have seen huge drops in power going too high octane. The way I see it is, if you are hitting your max targets(ign ect.) with 94 octane and a tune for 94 octane then 98 octane does not increase power. It is a far less violent combustion the higher you go. Light bulb is brightest before burning out theory. As long as you are not relying on your knock sensors your octane is suffice. Is this correct?

Given readily available fuel types/additives we can put in our E9Xs, you can increase hp by increasing the octane rating.
