Nice improvement from driving tips alone. I'm in a similar boat...trying to get better FE in my Tundra. It's an '05, 4.7L...and I average 16.5 city, and about 20 hiway.

A few improvements I've done, that might work for you, are:

Lighter weight engine oil. Mine calls for 5w-30, I used 0w-30.
Spark plug modification. Drill a 1/16" hole in the ground strap and index them.
Increased tire pressure. My max is 35psi, I have them at 45psi. Tires are heavily overrated in this area. They can handle 60psi no problem.
Installed an Aquatune. Still getting it dialed in...but hoping for 25% improvement from that alone....
