i have stock gears in my cobra and have not been able to granny it since ive had it on one full tank, i used to drive a civic so its hard to resist all the torque available now. around town i usually get 17mpg, on the freeway i see this thing do way better, and i know i did like 21 or 22 once but the rest of the tank was back to flooring it,lol I worry if i get gears what will my mileage be, heh but i do granny it alot but unfortunatly not a full tank of goin easy yet.( its hard
