Default Fuel Mileage
Ever since I have installed my cam, longtube headers, and underdrive pullies, I have had terrible gas mileage. I mean I do drive it kinda hard but I am getting around 10 mpg. Is this right or is there maybe something wrong with my tune or could it have to do with the O2 sensor prob with running no cats?

You're more than likely running rich, and the heavy foot doesn't help the situation. Its time for a tune bud..

If not, go get tuned. If so, go get a retune...
