Cutting weight will improve your mpg slightly but you would have to cut a lot of weight in order to see any noticeable changes in the environment you drive in. Weight reduction is far more effective in city driving, while aerodynamics play the largest role on the highway.
rrsussel aka dturbosol here on ecomodder, has did a lot more than work on his engine. He incorporated changing his driving habits, aerodynamic and other modifications.
"Try to run high IAT temps. I use a grill block"
"Run your tire pressure at 55psi to 60psi"
"Run with your windows up"
"If you do have AC turn it off"
lowered 2"
Here is his post on ecomodder of his build (

I read in one of these posts that his goal was to keep it under $6,000 invested. With that much invested to make 64.8mpg, it will only take ummmm 117,108 miles (8 years to the average driver) to make his money back. Only after that will he begin saving money on gas. He has done an amazing job on that car and is getting great gas mileage, but in the end the upfront investment just isn't worth it
