No worries, I'm just not sure how you had the custom tunes on the device since I don't show a download for it. Give these tunes a spin and if there is still a problem get with me and we'll make a new set.
As for the GUM, there isn't any reason to use it. The firmware hasn't had a significant update in a long time and the calibration update would just overwrite your custom tunes.
Take care.
