How about getting back to us when you have some real road test info to share? Otherwise, playing with your stationary engine with no way to put a load on it is a huge waste of your time, and ours. Your so-called results are phony because they don't duplicate real-world operating conditions, and running an unloaded engine at highway RPM is an exercise in futility, no matter how much name-calling you engage in. Shoot the messenger if you must, but your numbers resemble what comes out of the north end of a southbound Holstein, and you refuse to admit it.
