I don't really notice a power loss until 280F when the ECU intervenes. Prior to that there is a slight loss of throttle response and perhaps a very slight loss of power as the ECU adjusts the timing.

My non Z06 C6 had an oil cooler and it still ran 250-260s, people need to stop flipping out like little kids. I think water temp it got up to 230 or 240F.
Your 370 is not outrunning a GTR at 200F or 280F....
Just as a heads up, the OBDII system doesn't read the oil temp as one of its parameter. If you lose power, it's most likely because of the variable timing or car pulling time due to intake temp. It really isn't directly related to oil temp.
