How many times are you going to keep posting this nonsense? Your last thread proved you wrong, but keep going with it.
Again, if you want to run your SS on 87 knock yourself out. My car made a substantial increase going from 93 to E60 minutes apart on the same Dyno, but hey it’s all myth according to you. Oh and E is CHEAPER than premium AND 87 where I go, so I guess I’m saving money.
