At 23.5 MPG, you can sorta see what my driving habits are. It's just casual everyday driving. Even in that scenario the ECM is cutting power which can take my by surprise while making a turn or merging and having minor trouble keeping up with traffic (i.e., not as fast as anticipated).

I'm not sure I'm buying into that story from the tech whole heartedly. Yes the engine is going to cut back power indirectly by pulling timing as the intake temperatures rise, but not as severely as your car seemed to be experiencing. I mean I can beat on the car at auto-x or at a race track and have never really encountered the problems you are experiencing, and that was with the oil temp hovering between 240 and 260.
