  Previous studies of a three family Yukawa unified supersymmetric grand
unified theory (SUSY GUT) with SO(10) or Pati-Salam (PS) gauge symmetry
proposed by Raby and students show that this model is able to fit low energy
and inflation observables. However, the fit to low energy observables is not
great especially for $\sin2\beta$, and up and down quark masses. In this paper,
we show that by choosing PS as the gauge group and modifying the Yukawa sector,
the low energy fit improves significantly while other qualities of the model
are maintained. In particular, the lightest SUSY particle is the neutralino
with mass of order 300 - 500 GeV, the lightest stop and sbottom have mass of
order 3 - 5 TeV and the CP odd Higgs mass is of order 5 - 6 TeV, so we are in
the decoupling limit for the light Higgs. In addition, we reinterpret gluino
simplified model analyses by the ATLAS and CMS collaborations and find that the
most stringent gluino mass bound for our model is
$M_{\tilde{g}}\sim1.9\,\text{TeV}$. The current best fit point, consistent with
this bound, with gluino mass $M_{\tilde{g}}=1.9\,\text{TeV}$ has
$\chi^2/\text{dof}\approx1.12$, compared to the best fit point of the previous
model with $\chi^2/\text{dof}=1.90$. We find that predictions for the electric
dipole moment of the electron, the branching ratio $BR(\mu \rightarrow e
\gamma)$ and the CP violating angle in the lepton sector, $\sin\delta$, are
affected significantly as compared to previous results. In summary, we are
unable to rule out this model or place an upper bound on gluino mass accessible
by this run of the LHC because the $\chi^2/\text{dof}$ of this model is well
below $2\sigma$ even for a gluino mass as high as 2.7 TeV. On the bright side,
this means that this model is still viable and we might find low energy SUSY
particles in the near future.
