Ran a track day yesterday. About 2 hours on track.

My AEM boost gauge seemed to be reading normally at the start of the day but by the end of the day it was all wacky.

When I left the track sitting at idle at a light, the gauge is reading 30 Psi!!!! I'm only set up for 8 psi of boost.

Faulty gauge? Wiring? Something else?

I have same problem but it's opposite. Mine will only read fine at first then it gets hot it will read 14" of vacuum at idle. I don't think the car will run at 14" of vac

Maybe a vacuum tube became loose?

I remember something similar like that happened to me and it was just a loose vacuum tube.

Guessing you already checked the sending unit and connection of line?

Mine is crazy as well. I think it was showing correctly three times in a couple of months. Other than that, it shows way too high. Hopeless.

Seems to only happen in the heat. Was fine this morning.

That's the same with me. Perfect in morning. 30 drive later and it goes out of wack
