I have a 2001 ultra classic that I have upgraded from an 88 to a 95ci, andrews 37g cam, direct gear drive, vance/hines ovals as well as a stage II download and a race fueler (not tuner). I have a noticable decrease in gas mileage and my rpms are at about 4000 - 75mph. Does anyone have suggestions on how to bring the rpms down and recommendation on a race fueler or power commander???
