WEll, we do know that it isn't functional at WOT but it IS functional at cruise and a few other times.

The highest cylinder temps are when you run lean as in a lean burn cruise A/F ratio to save gas, deceleration initially as all the fuel is burning out, and of course if you run lean mixtures at WOT it will get really HOT.

But the engine uses fuel to keep combustion temps down under WOT, so I don't know about the EGR protecting the car at WOT.

I know DemonSVT studied the PCM controll of the EGR and can shed better light on when it is actually uses.
From what I gather it makes no impact on performance though.
