Need some help I installed my gagues last weekend and my EGT reading, when truck is off sits around 150 deg? Is this O.K. or did I do something wrong? Could I be seeing incorrect temp readings with it this way?
Thanks

mine does that then goes to zero when you turn the key on

carharttfarmer thanks for reply. Mine doestn't go back to zero when I turn on key it stays @ 150. Any suggestions.
Thanks

mine stays around 100* when it sits. the gauge is only designed to be accurate in the normal range. dont worry.

It will also be dependent on which gauges he has, my ISSPRO Pyro sits at 0 with the key off or on, until the motor is running, then it climbs to 300 while idling.

Early in the morning when the outside temp is 45-50 deg. F, I get within 2-3 degrees of that. When it's the afternoon and the sun is hitting the hood, it is about 125-150 deg.

I have autometer. This morning it was about 55deg. and when I turned on key it went to 125deg. Do you think I have sensor in too deep and its touching manifold? I tapped hole with 1/8 NPT. My buddy's goes to zero when he turns on his key.
Thanks

You might want to adjust the probe. When I installed mine, I pushed it in until the tip was at the bottom of the fittings and made a mark with a sharpie on the probe, then I installed the fittings and pushed it in as far as it would go, made a mark with a sharpie, and pulled the probe out, and split it in the middle and that was the depth I set it to so that the probe was dead middle of the runner.
