1993 GMC 1500 4x4 350?

[Brandel]

i have a 1993 gmc 1500 with a 350 and its 4x4. i want to get better gas mileage out of it so i would like to know the best, cheapest way. i was recommended a programmer chip but i cant seem to find one, so inputs would be well appreciated.
yeah it is a great truck, extended cab short bed, lifted 9 inches (6 suspension 3 body) on 35s, gets around 14mpg, but people told me a chip will get it about17 18 mpg

new 02 and air filter and ac delco spark plugs will go a long way to returning it to factory fuel mileage

its a 4x4 truck, you cant expect it to be great on fuel mileage

thats just how it is.

you should have a car on the side to drive when you dont need the truck if you need to save fuel costs that much
