So you're saying when it's saying I'm making yellow PSI I might only be making green PSI? Are these gauges known to fail in a way that causes them never to read in the red zone? Does this system coordinate with the homeland security color system?

What I want to know (from somebody familiar with the model) is what gauge readings are normal, and what the actual boost pressures should be normally. Even if I measure it with a gauge marked in PSI/bar, I don't know what to compare it to.

It's not a *real* boost gauge. It does not directly measure boost or manifold pressure. Really, it is more of an air flow rate estimator - it runs off the T5, not any sort of hose or fitting on the intake. And "maximum" boost readings (i.e., where the needle goes and what it is supposedly indicating) can vary by temperature, humidity and fuel quality.

This is applicable to manuals especially...

But of course you have an automatic, so you get 6.5 psi. Your gauge is reading right.
