accuracy of pressure reading on vafc
 

is the pressure reading(boost guage) on the vafc accurate? i am just wondering whether or not i need to buy a boost gauge since the vafc already has a pressure monitoring function. i like the fact that it has digital peak hold data. yes, i know that it reads in bar, not psi, but that is easy to convert anyways.

It's as accurate as your MAP sensor, which is what the ECU will read from which is all that matters.

Analog gauges fall prey to elevational differences. But, for a quick glance, they're great.

I use both (VAFC and a Autometer Ultra-Lite).

That's interesting, that's exactly what I was thinking about when I posted this:
