Sure - for cruising, just keep your EGTs as low as possible. Your thermal efficiency will go down, but your fuel economy will paradoxically go up.

You might also want to consider performing so-called jackrabbit starts from a dead stop, and see what that does with your fuel usage. For your engine, the slight increase in fuel usage, as compared to a more gentle acceleration, may be more than offset by the increased amount of heat energy per combustion event that is turned into useful work. This is how I am able to get well over 16 MPG out of my Dakota during city driving (the EPA city rating for my Dakota is 13 MPG). Just remember to keep your EGTs below maximum safe temperature, or you'll start melting or cracking things.
