    Default How to calculate boost pressure by MAF gs / rpm and Lambda?

    Hi, does anyone know how to work out the boost pressure by Maf / Rpm and Lambda.

    1.9tdi pd105
    Diesel 14.7
    Each cylinder is 474cc x 4
    Atmos pressure is 1040

    An example set of known data.
    AFR: 11.44
    Boost: 1990 mbar
    MAF: 500

    I need to work out how the calculation for boost using the above.

    Thank you
