    0v = 0kpa, 5v=304kpa I believe

    Not a problem:
    315 Kpa/5vdc= ~63 Kpa/volt
    To get to PSI you multiply the Kpa by 0.1450377
    Max Boost is 31.1 lbs.

    none of teh MAP sensors = 0kpa at 0 volts
    or atleast I havent seen one yet that did

    *usually* 0 volts
    1 bar = 10.33
    2 bar = 20.66
    3bar = 30.99

    and 5 volts
    1 bar = 94.34
    2bar = 200.00
    3 bar =304.00

    They all have a spec floor at 0.25 or 0.5V and a max of
    4.5 to 4.85 in the datasheets I've seen. Here is one (.png)
