  Lepton Flavor Universality Violation (LFUV) in $b\rightarrow s l^+ l^-$
processes is investigated in the context of a 331 model. It is shown that in
order to explain the experimentally observed deviations from the Standard Model
in these FCNC transitions, a non-minimal version of the model has to be
considered. We investigate the ability of this model in accomodating the
model-independant scenarios currently favored by global fits.
