I am not too worried about gas mileage but stock I was getting 14mpg in day to day driving and 16-17mpg highway with denali rims and 265/70r17. Now when I switched to 33s on 20s, I noticed it drop to about 13mpg city.

As of today I have installed a tune and electric fans, netting me about 10mpg city and 14mpg highway. It is not the tune or fans that is causing the gas mileage drop. I talked to the tuner and they stated that the O2 sensors are acting up. So that could cause my fuel loss, but I am on the hunt to get it back to 13-14pmg city. I am aiming for 15mpg since the tune and fans are supposed to help mpg.

I'm on stock 17s and 265 at's. I was averaging 13 mpg locally. I installed an Cai and new plugs and wires this weekend. I'm hoping for 15 mpg, exhaust and fuel filter are next on the list.

Got new O2 sensors installed and averaged 14.55 MPG on one tank and 14.8MPG on the second tank. Much better then what I was getting around 10! I am still aiming for 15MPG with 33s.
