This is why you throw away all changes, go back to stock, and only make the ones you understand.
Its annoying that nobody seems to listen.
what im trying to do is see changes that people have made and where to understand what they do. as im very new im looking and asking why something like that would of been done, as in theory to me i wouldnt do it like that. this is part of my learning process
