We present the latest predictions from AdS/CFT for $D$ and $B$ meson suppression $R_{AA}(p_T,\eta)$ and $v_2(p_T,\eta)$ in Pb+Pb collisions of various centrality classes at multiple LHC center-of-mass energies. Included in these predictions are systematic theoretical uncertainties due to the currently incomplete understanding of strongly-coupled energy loss and from mapping QCD onto N=4 SYM.
By comparing to baseline p+p data, we establish the inadequacy of current NLO schemes at describing the rapidity dependence of heavy flavor production. Using FONLL heavy flavor production, which does reproduce the rapidity dependence in p+p collisions, we then compare to current $D$ and $B$ meson measurements. Our results show good qualitative agreement with data, suggesting a consistent picture of strongly-coupled quark-gluon plasma formation from low-$p_T$ observables to high-$p_T$ observables.
