Here is Mark P's EGT. It does not even show any movement in EGT
<center><img src="http://ctny.audiworld.com/mark/s4/ecux/graphs/egt_f.GIF"></center><p>If it is normal for EGT to be high w/ Stock then there is one more reason to go with a 3rd party Chip.

No EGT graph there - the ones in your 1st post were below 980
which is safe (according to the engineers that designed it that way). If it is going above 1000 deg C then yes I'd probably be concerned, that's not supposed to happen. And yes GIAC (along with other chips) in general will lower EGTs substantially over stock.
