It idles at 1400 RPM and I can't get the IAC anywhere near the recommended percentage. Can the Dominator use Alpha-N for idle below a certain RPM/TPS and switch to Speed Density mode above this point?
    This is going to sound nuts. Your cam isn't that big. Alpha-N isn't needed. Cylinder to cylinder balance has a larger effect on idle quality than cam size. I've done more than a few engines with cams that size or larger, and they work fine in VE.
