1 bar vs 2 bar MAP sensors?

Ive been going over this in my head for a couple days and was wondering if anyone here could shed some light on the matter for me.
OK - so NA cars come with 1 bar MAP sensors and most turbo cars come with 2 car ones (some with 3 bar).
Now all a MAP sensor does is sense the manifold pressure and convert this into a voltage and output it to the ECU which then looks up values in a table and supplies fuel and timing accordingly.
So how do 1 bar and 2 bar MAP sensors differ? Now im unsure about what range of voltage output to expect (anyone know?) but would i be correct in thinking that a 1 bar MAP outputs say 0-5v on a certain (possibly linear?) scale, and a 2 bar sensor say puts out 0-10v on the same scale.
Or, is it that these 2 sensors output the same voltage range, say 0-5v, but the scale is different (yet possibly still linear)?
Can anyone shed some light on this?
