So after driving the car around a bit today, once it got really warm I noticed throttle response virtually disappeared with Tune B using Map 1. Throttle or power (I'm still not sure) from 2-3K RPM was just dead, until 3K and then the car would pick up steam. My oil temps were approaching 220 because of the slow moving local traffic I was stuck at, going up a bunch of hills, lights, stop signs, etc.

It won't go above 220 because of the oil cooler, but I'm suspecting that the ECU is seeing extra timing dialed in and pulling even more timing in the lower RPMs once the oil temps rise a bit. I doubt it's the throttle map, since even if I buried the throttle the car wouldn't really respond in the 2K-3K range. When I switched to map 2, the car drove fine and dandy.

I'm having the timing pulled back on map 1 to see if that fixes it. Anyone have any ideas of their own? Is the timing increase causing this lack of power or the throttle map being adjusted?
