The more mods the more power! It's just an average based on customer dyno sheets I've seen. I've seen some customers make less on 91, and some more. The lowest I've ever seen is 30rw and the highest 90rw vs. a baseline. So the type of dyno, conditions, modifications, and the car itself are also very important factors on low octane 91 fuel.
