    For2.5 bar MAP sensor 12580698 try this:

    MAP Scaler 207.65625
    MAP offset 9.00

    I think that is right from the factory tune settings for the ION Redline.

    Do the 2.5 bar sensors read okay to 20 psi boost on our cars ?

    I tried a 3.3bar sensor and it was a waste of money, couldn't tune VE off boost with any consistancy..
