    Question Whipple Raptor - Low Compression Motor - Surging

    2013 Ford Raptor Prerunner

    9:1 Compression Ratio
    MMR Ported Heads
    Stage 2 Whipple

    Second the truck makes boost it goes super lean and cuts out/surges.

    Any pointers on how to adjust for this?
    I started with whipple base tune from repository, used the injector data from my 60# injectors, and this is where I am so far.

    I haven't had much to do with the earlier Mustang but you will need to log a lot more information, Mapped points, Throttle error, all spark and fuel TQ limits, ETC effective area, IPC error.
