We present a procedure for tagging boosted semi-leptonic $t\bar t$ eventsbased on the Template Overlap Method. We introduce a new formulation of thetemplate overlap function for leptonically decaying boosted tops and show thatit can be used to compensate for the loss of background rejection due toreduction of b-tagging efficiency at high $p_T$. A study of asymmetric top pairproduction due to higher order effects shows that our approach improves theresolution of the truth level kinematic distributions. We show that thehadronic top overlap is weakly susceptible to pileup up to 50 interactions perbunch crossing, while leptonic overlap remains impervious to pileup to at least70 interactions. A case study of Randall-Sundrum Kaluza-Klein gluon productionsuggests that the new formulation of semi-leptonic template overlap can extendthe projected exclusion of the LHC $\sqrt{s}$ = 8 TeV run to Kaluza-Klein gluonmasses of 2.7 TeV, using the leading order signal cross section.
