Sodium filled like on the DET engines or inconel can get away with higher temps.
900°F is a joke.

how EGTs work. It is a good thing.

As ashton said also your tune and the way your going about tuning isnt the best.While it's not the best way to do things, it is at least marginally decent. It can't really be tuned for anywhere else but WOT this way but it should at least work.

EGTs are one of the best ways (if not the best way) to tune timing. In my opinion you typically tune fuel mainly with Wideband O2 readings, and you typically tune ignition mainly with EGT readings.

No tuner tunes off of egt's again its only used to tell you whats going on.98% BS.
