Demon, you must live in the boonies or something to get away with the driving you speak of
Not for us suburbanite dwellers unfortuantely ...
I'm currently seeing about 280-300 miles/tank in mixed driving. Thats with new plugs/fuel filter, clean UIM and TB, and dirty LIM and (filthy)stock air intake.
Once I clean the LIM and put my new intake in, Im sure my high speed mileage will improve, at speeds where the secondaries are open (above 80 mph) and airflow is important.
