No direct aviation experience here, but on the test stand the placement of
the EGT thermocouple has a surprisingly large effect on the temperature
reading. Not only distance from the port, but also depth into the runner.
Peak temp will usually be at the centerline of the runner, but having a
thermocouple stuck that far into the stream increases the risk of breakage.
Pull it back, and the temperature drops quite significantly.
