Has anyone done any actual A-B-A testing on this? I know since i advanced my timing and stepped Tank up to 91 octane about a year ago i pull an extra 1.5-2 MPG but I'm thinking if this works then some octane boosters may make a difference as well Either good or bad. Anyone on here tried octane booster to boos fuel economy? If not would anyone mind doin it to see if it changes anything?
