Thanks Superchow....Thats right on "Topic"! When I first read "off topic", I thought you were gonna try & suggest VG's or HHO generators! (I really hate both of those)

Thanks to all for your suggestions!! I have been driving keeping the RPM's <2500, it's funny that the HP/Torque curve I found Starts logging data at 2500 RPM. I wish I could find a Brake Specific Fuel Consumption curve for my engine. I would almost be willing to bet it has 2 areas of "Sweet Spot" on it, one for 3 valve ops (<4200 RPM) and one for 4 valve ops. So I guess if I treat it like a 3 valve engine, I'll be safe.

Also, My gearing is not very "Tall" on my car, I don't have specifics, I just know that at highway speeds 65 or so I'm at 3200RPM, so the DCFO thing has me wondering? Is there anywhere I can find out this setpoint? Does the ScanGauge have this? I suppose really though, a very small percentage of my driving requires engine braking, and if my foot is completely off the gas pedal, I gotta believe my fuel consumption is in the 1/3 GPH or less mode. So at 65, thats 200MPG for the time I'm engine braking.
