  The resummation calculation (ResBos) is a widely used tool for the simulation
of single vector boson production at colliders. In this work, we develop a
significant improvement over the ResBos code by increasing the accuracy from
NNLL+NLO to N${}^3$LL+NNLO and release the ResBos v2.0 code. Furthermore, we
propose a new non-perturbative function that includes information about the
rapidity of the system (IFY). The IFY functional form was fitted to data from
fixed target experiments, the Tevatron, and the LHC. We find that the
non-perturbative function has mild rapidity dependence based on the results of
the fit. Finally, we investigate the effects that this increased precision has
on the measurement of the $W$ boson by CDF and impacts on future LHC
measurements.
