    Boost in psi

    So i fitted my boost gauge today usually read in bar rather than psi! It reads -22 when just ideling and then when i boot it, it reads 11psi peak then settling around 9psi! Is this correct for standard 1.8t 190 bex?

    If I remember rightly from my RS Turbo days, 14psi = 1 bar of boost to give you an idea..
