I have read that this item is a major plus when forced induction is introduced to my SVTF. I have read the description of it and I am still somewhat confused as to what it does better. I understand that my car has a factory knock sensor which I am sure works fine, but I am still curious as to why purchase this. I am not going against anyones better judgment, but doesn't it do the same thing as the factory knock sensor? Please bear with me as I have severe ADD and sometimes over look small things when it comes to things like this. If someone could explain to me its main purpose over stock, I would appreciate the help.
