  We present measurements of superconducting transition temperature,
resistivity, magnetoresistivity and temperature dependence of the upper
critical field of Ta$_4$Pd$_3$Te$_{16}$ under pressures up to 16.4 kbar. All
measured properties have an anomaly at $\sim 2 - 4$ kbar pressure range, in
particular there is a maximum in $T_c$ and upper critical field, $H_{c2}(0)$,
and minimum in low temperature, normal state resistivity. Qualitatively, the
data can be explained considering the density of state at the Fermi level as a
dominant parameter.
