I know that's how the Isspro EV works. Not sure on the EV2, but the Performax is set up different (can't remember the details now) to give a more accurate display of what the EGT is.

That makes sense and fits into what I'm seeing. My pyro is either EV or EV2, can't remember which. The day I noticed the low reading was when I parked in the sun on a 95 degree day and the pod was getting direct sunlight.
