K&N intake, dynomax catback exhaust, jet stage 1 chip, no lift or bigger tires(beefiest michelens you can put on stock rim though if taht matters)

13-14 mpg with a major lead foot

before the chip, i would push 11 mpg, before the intake/chip, 15+....my conclusion is that because the intake takes in colder air, the engine will mix more fuel and air because the air can handle more fuel...equaling less mpg, if that makes any sense

the jet chip definatley helped, those chips learn your driving style and program the computer for best power/efficiency...i can romp on the gas 24/7 and still get decent gas mileage for some reason

bored throttle body coming in soon, that could change it yet again, who knows
