ok first off a chip isnt going to do much yes it can adjust the speedometer for larger tires and change shift points and get rid of your top speed. but by the time you go through your money the power and mileage isnt really worth it in my opnion. for bad gasmileage there are lots of things to do for it like, new plugs,wires,fuel filter,fuel system cleaner,adjust your
TPS, correct tire pressure,and last but not least stay off the skinny pledal as much as possible
