    Procharged 2014 Mustang starts, won't hold idle

    2014 Mustang 5.0 M6
    Ford Racing Cobra Jet intake manifold
    Ford Racing big oval throttle body
    D1SC Procharger
    Ford Racing 47# injectors


    The vehicle starts but quickly dies, the kit has the MAF in the intercooler which is very strange.

    Any input is appreciated, this is the first 5.0 Mustang I've done with boost.
    Attached is the baseline N/A tune that the vehicle started with and "tune3" is the current file with the changes I started to make.
    Thanks!

    Are you referring to the Effective Area table under the Throttle Body Model section?

    Th effective area and predicted tables need to be changed for an aftermarket throttle body.

    Is there a formula for making the changes?

    If its a throttle body that isn't defined in another OEM tune this method can get you close until the proper DMRs can be logged to correctly calibrate it.

    Make your life easy. Throw the stock throttle body on it, do all your normal fuel, maf, and spark tuning, first. Then go back and add the throttle body to it.

    Thanks for the link Witt, I'll give it another shot tomorrow.

    PST, unfortunately the stock throttle body no longer works with the new intake manifold.

    More important table is predicted. You must buy SCT to do that for logging.

    I don't have anything from SCT, I've been pondering a dealer's license.

    UPDATE: Car idles like it should!

    To anyone else having this issue use the stock Cobra Jet read to get you started with the throttle body tables.
    Thank you everyone for the help and very much to Eric Brooks for uploading a stock Cobra Jet read!

    It's VERY pricey.
