This subject has been beat to death but wanted to share info.Long ago and I don't remember who it was BT, Rockford but had my radio flashed per instructions this was way before line levelers so had had Bin 135off recently reinstalled 6.5 and PSM been getting good results but not the great was after finally decided to try stock ultra flash 00off this has made a world of difference and have same tune with bike running or not. Bass and cleaner clear Vocals side note only running 1 loc so fade is useless

So many times been told Bin file don't matter so all I have to say is BS.in my opion
