I was only amplifying the voltage when measuring shunt voltage drop with the ADS1115
With the INA219 I'm using ESPEASY where there doesn't seem to be an option to adjust the gain.
I'll look again this afternoon.
Good chance you won't need to, just using the default library values I calibrated mine by trial and error using a DC clamp meter and tweaking a calibration constant I had programmed in, not sure if you can do that with espeasy though?
Mircopython library doesn't seem to return such stable values on my setup now though.
