  We present the first global tuning, using GENIE, of four transverse kinematic
imbalance measurements of neutrino-hydrocarbon scattering, both with and
without pion final states, from the T2K and MINERvA experiments. As a proof of
concept, we have simultaneously tuned the initial state and final-state
interaction models (SF-LFG and hA, respectively), producing a new effective
theory that more accurately describes the data.
