You should not be indiscriminately playing with the modulator pressure. Consider it a last resort if you cannot get the vacuum system to provide sufficient vaccum to the modulator.
The adjustment of the VCV should be your first mode of attack. Adjust the VCV for more vaccum to the modulator and the shifts will soften. 13" at idle does sound reasonbly close to the spec.
You can test that valve with the engine shutdown if you've got a Mityvac. You can also adjust the valve for more vacuum.
