That's getting down to semi-truck mileage.

Sounds like you have something else going on (unless it was always like that), so the chip probably wouldn't help much. I'd find out what the problem is first.
Fuel filter, air filter, plugs, wires, MAF sensor, are just some of the things I would look at.
