    Roush Log review air flow realistic?

    2017 gt,
    roush phase 2 kit with phase 1 pulley (85mm).
    2020 gt500 injectors.
    Mild Ported lower mani, port matched runners to cyl heads.
    Untouched roush maft curve,
    Ambient Temps mid 90's.
    Stock cats/ 3" catback. Normal bolt on setup minus ported lower

    Is this airflow realistic for this setup? Has always been consistent at 77 To 78 lb/min in warm weather. Air load has as well at 1.6.

    I ask because I'm getting about 8 or 9 percent rich trims at full tilt and fuel pressures are accurate per external sensor/ inj data is from oe Ford gt500 tune. Have not confirmed map yet but suspect it might be off as ill hit 100kpa at 0.80 airload at pt but wot of 160kpa seems inline for this pulley.

    Any thoughts or areas you would recommend to address the overfueling?
