    Idle surging and throttle closing on cammed 2014 gmc.

    Those this trucks have a RAF table or something similar? I can't make it to stop surging wideband it's on airfuel it's at 14.5 to 14.7 but it stills surges. Now at WOT 1>2 shifts good and 2>3 its starts to close the throttle, just on shifts it closes like 30% and re open back.
    I did some changes on the driver demand but it gets a little frustrate.
