Someone might correct me, but I don't think there is an actual pyrometer in the exhaust system. EGTs are estimated from a look-up table based on load, AFR, RPM etc.

Diesel EGTs have massive variation. Typical turbine outlet temps would be ~150C @idle

300-400C general cruising, 650+C at maximum power.
