I cruise at 15.5 AFR even with the turbo and my EGTs never get above 1400 at cruise (last time I checked). I just dont think there's enough gas flow volume at cruise rpm (<4000 rpm, light load) to generate high EGTs.
My next commute I will try to pay attention though. I'm pretty sure they're between 1250 and 1350 absolute max at cruise. bung in the collector pre-turbo.
