    Mustang 5.0GT 2017 Axle ratio change

    Hello.
    What tool can i use to change axle ratio in this car? There was gear 3.31 and its changed to 3.73.
    I got ProCal3 but i cant change configuration until i load calibration file, which i cant get becouse voucher code from fordperformance was used by previous user (i dont have contact with him). Will i be able to change this with MPVI2?

    The vcm scanner will let you input new gear ratio in it and it does not cost credits but you will need to buy the Hp tuners mpvi2
