I have the MPx catless downpipe that came with the EGT bung so thats where my placement is which is right behind the 02 housing flange.

Egt's should be installed in the exhaust manifold only 2-3 inches from the head, not in the downpipe.
If you would of installed it in the exhaust manifold you'd be seeing 16-1700F temps at wot.

Hes right that is the most accurate place to measure them at.

The reason people put it in the down pipe is the heat doesn't destroy the sensors as fast, but its no where as accurate as in the manifold.
