That's the good advice again. But the difficulty in finding the right range using a butt-o-meter is the reason for getting a vacuum gauge (to judge where optimal BSFC is), a tachometer, and--as an option--an MPGuino (to see the effects on economy more quickly than with tank-to-tank method).

But I have to think you'll see improvements doing what 2000neon says.

See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
