Ok I'm can't find anything that's helping me. My truck is getting 11mpg. My question is why. It's a 98 chevy1500 4x4. 5.7 auto. I've done a tune up. Replaced fuel filter. I've put a throttle body spacer on it. I've capped the silencer on the air box. It has 3.42. 2 in lift. Or leveling kit. And 265/75r16 on it. I've hear people are getting 16. And some are not stock. But I can't figure out why mine doesn't. It's killing me. Anyone know anything?
