Yup they do. It could be the vanos, but it could also be your mind playing tricks on you. I think the torque curve is supposed to hit at like 3200 though so it sounds more like the vanos.
I really can't coment on what it should feel like because my engine doesn't have the vanos and I've also go different cams than the other 325s.
