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.

You're right. It is a very noticeable problem, and it is pretty bad during the summer. When I give it more gas, the exhaust gets loud, but the car doesn't budge (i.e., feels like accelerating in too high of a gear).

As weird as it sounds for ambient temps averaging upper 60s to lower 70s this time of year for daily driving, I may get one. Either way, I'll be getting one once I pull the trigger on the F.I. project early next year. I've been a bit hesitant to go F.I. because of these issues. Based on your experience, if the oil cooler keeps me under 200F in daily driving conditions and resolves these power cut issues I'll be happy!

That's the weird thing. Some people get it and some people don't. Have you seen my YouTube video demonstrating the cut in power? It doesn't take hard driving to notice power being cut. However, as others may have jokingly mentioned, simply drive above 3k RPM and it'll be fine.

Yup, same here. And it's usually under 3.5K, correct? Oh, and it's really bad if you're stopped on a serious incline and try to get going.
