Does anybody know if the turbo boost gage on first generation GT's is an actual pressure gage, or is just run by the ECU? I'm asking this because I suspect I might have a crack, but the PSI indicator shows normal pressure.

The guage is highly inaccurate from what I've been told. I think it shows an estimate of boost rather than an actual pressure reading. Hope this helps ya out.

Thanks for the info. So then I can assume that whatever the guage reads is the actual pressure in the turbo, right? That is, if the controller is not shot, which I don't think.
