Broadway Limited J decoder CVs

[NW Modeling List]

I have a HO Broadway Limited class J engine from 2005 ish.  I am trying to adjust the sound volume (it’s too loud) and adjust the speed (too slow compared to my A).  Does anyone know which CVs I need to change?  Is there a factory list of the CV settings available?  Since it is an older engine Broadway reps couldn’t help much.
