I have been wanting to get this turbo timer for a while but I am not sure how good it is. Does it come with everthing that I need or will I have to get some kinda harness to make it work? Thank the like is below

It has to be spliced into a few lines to make it work. There are harnesses you can get for some cars (takes care of power supply), not sure any audi has one. Someone should have a detailed listing of what wires you need to tap into.
