For the non-equilibrium, ionizing (NEI) conditions present in the X-ray gas of young supernova remnants, the iron peak elements are often observed to be in intermediate charge states whose emission lines are not adequately represented in the current generation of plasma codes. We report on our progress in generating with modern atomic physics codes the data necessary to model accurately the NEI X-ray spectra of these ions. We will compare newly calculated spectra against deep Chandra and Suzaku observations of Tycho's supernova remnant, allowing for the first time a reliable measurement of the X-ray emitting mass of iron, as well as other less abundant iron peak elements (Mn, Cr, and Ni).
