s are you running? You don't tune by EGT, you tune by A/F. When you start running higher boost, the EGT will go up.
If the A/F is correct or fixed say 11:1, the timing that is tuned in the chip and the amount of boost will affect ext temperature. I have real world experience on this. I data logged my A/F on the wide band and have a peak holds egts.
JWT says that my egts are correct. I have friends with 800-900HP supras and they hit higher than 900C in the 1/4 mile. You can be conservative on EGTs or not. 800-900C is the normal range depending on the boost, load, a/f, timing, exhaust back pressure. I am running about over 500rwhp at my boost pressure. I have seen 880c to 900c on mine. Also outside air temperatures will affect the egts. Cold days will have colder egts than hot days.
