Thanks Xair - I realise that the EGT probe needs to remain rigidly fixed into position. That's why I used a little dab of silicon to make sure it couldn't budge after I bent it up a little so that it was just the right length. It's secured to the Turbine with the supplied bracket etc.
Smithy advised me to look for a potential hot-spot at 5 o'clock - the hole for the EGT is at 10 o'clock ex-factory. I'm thinking that it makes sense not to position the EGT right on any natural hot-spot to avoid getting a false (higher) ambient temperature reading and potentially causing an unwanted over-temp shutdown when the rest of the Turbine is running well within temperature limits.
