Hello guys and congratulations for this reall helpful forum! I have a '98 A3 18T / AGU engine and it's remapped by ABT (193ps). Recently i noticed something weird on the intake manifold. There is a small hose that is not connected on something and it's tapped by a screw :/ I have no idea what is this,but looks not so normal Can somebody tell me what this can be and where should be connected? I post two photos,so you will see exactly what i mean. Another question is if a N75 J valve could help me for little more boost.Is it ok to switch from my ordinary one? Thanks in advance,keep the good work!
