This is probably not a 911 situation, but I need help. I installed some gauges last December. They worked just fine for 8 months, but now all of the sudden my EGT gauge is reading around 600degs low. If I am just cruising, it will drop all the way to 0. If I am going up a hill, it will go up to around 600degs. I have not lost any power. My boost gauge is working fine. You can look at my sig to see all of my mods. I should have higher EGT's than this! Can anyone help me please!
