As soon as it cooled down a bit heading towards melbourne (same day and about 30c around there instead of 32c) the egt's dropped back to around 385c and then in the evening was back down to 365c as we headed towards the valley(home).
Conclusion was ambient temperature can and does affect egt's(in our vehicle), add other variables like head winds/side winds and affects it even more.
