this is a sign you likely have a bad O2 sensor or a wiring issue related to the sensor.

I replaced the 02 sensors and fixed all the wiring, but I keep getting the P0175: system to rich code after 20-30 mins of driving it comes back on. Is there any help or fix for this ? Do I need to modify my parameters more ? Any help is appreciated

did this run without codes for a period of time on this same tune?
Replacing the sensors without testing everything was a tricky move. It could be wiring, harness, etc.
You previously indicated getting codes for O2 stuck rich, which is not something the tune can do or cause.
