Depends on what you mean by PIG.Just picked up a used 2003 Dak 4x4, quad cab with the 4.7L engine. This thing is a pig on gas. Have read some older threads and seen some people list generic mods ("exhaust, tune, etc.") but am curious as to what specifically I could do to get some better gas mileage. What sort of exhaust mod? What sort of engine tuning? Any help would be appreciated! Newer to the truck world. Not expecting 40mpg but any help would be great.
I get about 16 in town and 19-24 hwy (depending on load and headwind) that's about the highest you'll see out of it. Pulling my camper I get 12.
mods that help. Cold air intake. Bigger throttle body. High flow y pipe (biggest choke in the system) High flow muffler. And a decent tune for mileage.
That's about all you got for mileage options.
If you have any kind of lift on the truck none of that will really make a difference, the drag from the oversized tires and just the lift in general drop mpg.
