You can set everything in config.json configuration file. For your purpose you should write something similar to this in config.json:

{
  "frequencies_ranges": [
    {
      "start": 420000000,
      "stop": 426000000,
      "modulation": "fm"
    }
  ],
  "ignored_frequencies_ranges": [],
  "device": {
    "ppm_error": 0,
    "tuner_gain": 0
  },
  "scanning": {
    "noise_level": -7.9,
    "bandwidth": 2000000,
    "samples": 10240,
    "fft": 16384
  },
  "recording": {
    "squelch": 5,
    "min_recording_time": 1,
    "max_recording_time": 60,
    "max_silence_time": 1
  }
}

To increase gain you should change device.tuner_gain value which is also stored in config.json file. I hope that all names of parameters stored in configuration file are clear. All of them could be changed.

Meaning of all parameters you could read in help.
