hey maye, if your talking about the electronic gauges I installed them in my bf f6 about 10 months ago. just hook the boost sensor up to the BOV line and you will need a few fittings (T-Piece) for the oil pressure sender as you have to have the original one installed aswell otherwise the car wont start. I done the boost gauge myself but got the tuner to put my oil pressure sender in as its in a real *beep* of a place.
