I tuned the carburetor on my gasoline powered suburban with the aid of my AEM wide band O2 meter for lean burn and it made about a 20% improvement over a properly tuned carb.
It works.
You do not want lean burn at high load, I burned all the exhaust valves on a fuel injected engine because I didn't know how to make it run rich at high load.
