200 boost

[Lawrence C Leung]

Gauge reads absolute pressure. Therefore, engine not running, system on,
the gauge should (and mine does) read 1.0 at sea (and most everywhere
else) level. According to SJM's site, max stock boost is about 1.43 bar
on a 200Q or about 6.3 lbs of boost, rather conservative, by most
anyone's standards.
