After I installed a PBR300 and Infiniti Kappas, I still had distortion at volume. I don't know the stock settings, but I printed out and had the dealer use the flash instructions in the sticky in this section titled, "Sticky: 14-15 Harley Radio FLASH Best Procedures Again!". Worked very well for me; cured the distortion problem and I have clear tunes at speed.
