Before I installed my BUDGET Y I was getting 220 to a tank(16.5 gallons). After the pipe was on, but the O2 sensor was just zip tied to the car cause of bad fittment, I still got 220 miles. After the 02 sensor was fitted back in on the very next tank I got 260 miles, during which I punched it 4 or 5 times a day(1 a day before that), on 15 gallons. Right now I just put on 100 miles and I'm at 3/4 full, before I had about 120 to a half tank...

oh, btw, if you haven't bought the sensor yet... www.oxygensensors.com , and put in your car info, order the OEM replacement sensor... 65 dollars shipped to your door, you will NOT beat that price, and it even comes with anti-seize
