How can i revise geometric_controller parameters?

[Tfly6]

This is my launch file in the below.

  <node pkg="geometric_controller" type="geometric_controller_node" name="geometric_controller" output="screen">
  		<!-- <param name="mav_name" type="string" value="$(arg mav_name)" /> -->
          <remap from="command/bodyrate_command" to="/mavros/setpoint_raw/attitude"/>
          <param name="ctrl_mode" value="$(arg command_input)" />
          <param name="enable_sim" value="true" />
          <param name="enable_gazebo_state" value="true"/>
          <!-- <param name="max_acc" value="10.0" /> -->
          <param name="max_acc" value="8.0" />
          <param name="takeoff_height" value="$(arg takeoff_height)" />
          <!--Params specific for Iris copter-->
          <param name="attctrl_constant" value="0.3"/>
          <param name="normalizedthrust_constant" value="0.125"/>
          <param name="normalizedthrust_offset" value="0.1"/>
          <param name="Kp_x" value="10.0" />
          <param name="Kp_y" value="10.0" />
          <param name="Kp_z" value="10.0" />
          <param name="Kv_x" value="5.0"/>
          <param name="Kv_y" value="5.0"/>
          <param name="Kv_z" value="5.0"/>
  </node>

I have two questions:

1. Based on the comments in the reference file, I modified the normalizedthrust_constant parameter to 1/max acceleration. While it runs, the drone exhibits significant oscillations. I'd like to know how to properly tune these parameters (attctrl_constant, normalizedthrust_constant, normalizedthrust_offset)
2. Should these parameter adjustments differ between simulation and real-world flight tests?
