I've thought about that...but there is no slippage of the SC clutch, which I personally think I would feel especially under load. I am going to check wiring connections tonight. If there is an intermittent short/bad connection then there would be no codes stored because it fixes itself when the connection becomes good again...but I don't know if it is a short because it very evidently a temp issue as the problem only occurs once the engine warms up...and gets to 'running' temps although those temps are quite high (192F under full load w/ SC engaged and 172F during normal running w/ SC engaged or disengaged)

I think I just talked myself in a circle back to square one...I am still going to check the wiring tonight for solid connections incase the IAT sensor is intermittently shorting out... who knows.

All I know is I want my car 100% by track day damnit.
