Fetrotech is a plug-in tool for PCMtuner, and it has two types – Silver and Black. Fetrotech Silver must work with PCMtuner Tool, while Fetrotech Black is a standalone tool.
A user shares the way to make Fetrotech Silver work alone:
Do a little modification, that is the difference between black and silver. much more comfortable work.
Bridge the two points.
Look at it on the other side with no difference.
