Here's the info....>>
Posted when I first posted this:
Running the calc's on this and subtracting for atmospheric pressure yields about 17.5-18 PSI (with my system on my gauge) or 1.2 bar give or take a little.
The 2200+ millibar reading is because: a mean atmospheric pressure of 29.92 inches (760 mm) of mercury at a temperature of 15°C (59°F) in dry air at sea level. This is also expressed as 14.7 pounds per square inch (PSI) or 1013.2 millibars (MB) at the same temperature. So...Vag readings are in addition to atmospheric pressure. A plus 1220 milibar reading (shown here) over atmospheric = 17.74 PSI (exactly what my gauge reads) at max boost. Your readings may vary depending on IC/intake/exhaust configuration.

Here's manifold pressure, before and after......>>>
