I’m thinking injector flow to correct rich is to increase the injector flow rate.

For example the WBO2 is showing AFR’s averaging 12.4 with an injector flow rate of 22 lb/hr. After increasing the...

Everyone tunes differently.

Starting over with a stock tune, with the bare minimum of changes ( for example: fuel injector flow for 18 psi fuel pressure regulator) can solve many problems.

Typically the 1995 4L60E will have a PWM Torque Converter.

The Base Bin Tune file does not have PWM Torque Converter Flag set.
