  We present a method that allows enabling Matrix Element Corrections (MECs) in
Pythia8 with MC@NLO matching, without incurring double counting. MECs are an
interesting feature that may contribute to the accuracy of theoretical
predictions, alongside matching and merging. We directly compare our method to
a specific choice of settings in Pythia8, which can remove double-counting for
MECs in certain processes. We show results by taking the ttW process as an
example. This choice allows us to study the impact of decay MECs in the 2SSl
and 3l final states. We find that jet-related observables receive these
corrections unevenly throughout the phase space. They can contribute up to $\pm
6\% in certain regions.
