    Possible fuel cut?

    I am trying to understand why my tune is acting like fuel cut? in my log it happens at 8:46:42.095 - 8:46:44.805.

    my tune has been working great but one day i started doing this fuel cut after i made a VE change.
    the wide band in my hist and guage shows rich but instantly go lean at 235kpa

    My build is:
    411 ecm
    6.0 with 6.2 heads
    ict billet ls3 intake
    BTR stage 3 turbo cam
    160 lb ID injectors
    twin 340 lph fuel pumps in tank
    VSR 80 mm turbo
    boost leash controller on ref or co2
    4L80e (built with d3 brake)

    feel free to ask about any other mods

    It says if you look under edit then calibration details that it is a P01 computer. What if you try under Fuel then Cutoff to raise you rpm limit to 7000 and resume at 6990. And the same thing for the VSS. And what if you set your DFCO to enable only above 250 degrees. It shows your commanded AFR in the log is .48 lol. And your inj. duty is 1400%. seems a little high.
