    Call me anal for this level of record keeping but here are my detailed results for ’07 so far along with total results since I’ve own the car. The mods to date (in sig) really haven’t made a noticeable difference. The best I’ve ever averaged for an entire tank was 27.2 and the worst was 17.9. I guess I would be considered a spirited driver, on the 4th set of tires.

    Id luv to tell ya but i cant. Some tard broke my fucking gas cap while i was geting gas one day. Its not the actuall cap, its that tiny metal peice that the tip of the gas pump pushes down on so gas can go into the tank. Its not closing all the way so if i go past half tank, gas starts spilling out of it.
