You have 3 possibilities:
a) Your car is chipped and have a 2.5 or 3.0 Bar boost sensor.
A 2.5 give .7 Bar and 3.0 .6 Bar because.
The output voltage from the sensor is 4.9 or 5.0 Volt
for 2.0 Bar (original), 2.5 Bar or 3.0 Bar.
and no-one cares about telling the display about that.
With a IA III set You expect 2.3 Bar at max. and the
gauge will read 2.3/2.5 * 2.0 = 1.8 at max boost.
b) You live on a mountain where the pressure is lower
c) You have a misreading sensor/boost gauge
