  The root of most of the technicolor (TC) problems lies in the way the
ordinary fermions acquire their masses, where an ordinary fermion (f) couples
to a technifermion (F) mediated by an Extended Technicolor (ETC) boson leading
to fermion masses that vary with the ETC mass scale ($M_E$) as $1/M_E^2$.
Recently, we discussed a new approach consisting of models where TC and QCD are
coupled through a larger theory, in this case the solutions of these equations
are modified compared to those of the isolated equations, and TC and QCD
self-energies are of the Irregular form, which allows us to build models where
ETC boson masses can be pushed to very high energies. In this work we extend
these results for 331-TC models, in particular considering a coupled system of
Schwinger-Dyson equations, we show that all technifermions of the model exhibit
the same asymptotic behavior for TC self-energies. As an application we discuss
how the mass splitting of the order $O(100)GeV$ could be generated between the
second and third generation of fermions.
