The CUJET Monte Carlo Jet Energy loss model is applied to predict the jet flavor, centrality and density dependence of the nuclear modification factor $R_{AA}$ at RHIC and LHC. Running coupling effects due to combined $x$, $k_\perp$ and $q_\perp$ evolution are included for the first time in the dynamical DGLV opacity expansion framework and are shown to provide a natural dynamical QCD tomographic solution to the surprising transparency of the quark gluon plasma produced at LHC as suggested by $p_\perp>10$ GeV $R_{AA}$ data from ALICE, ATLAS, and CMS.
