If you're just running a normally aspirated engine then you'll only want
a one bar sensor, 'cause you won't get a manifold pressure above
atmospheric.  If you run up to 15 psi boost then you'll want a two bar
sensor, and if you run up to 30 psi boost (God help your engine!) then
you'll need a three bar sensor.  (and an engine rebuild soon i guess)
