Make sure your air filter is clean, your plugs are fresh, quality gas, fresh oil, equal tire pressure and a GOOD alignment. When is the last time you had your fuel filter changed? Definatly check your alignment if you haven't done it recently, having even slighly too much toe-in or toe out can really screw with your fuel economy.
That's still not great mileage unless you're rocking a gt35 or bigger. I would average 20 mpg on a head/cam hybrid with 272s and a GT30R turbo. I hit my 7500 rpm redline at least once daily. No more than 75-80 mph on the freeway but I would get to 75 really quick.
