To anyone with knowledge of the S3's....
or aftermarket cams in general. I know that the idle is a bit rough, compared to stock. But do these cams cause a slight change in the smoothness of the engine (both under acceleration and at a constant speed). Because I feel like the engine isn't revving quite as smooth as before, and I don't know if that is due to the cams... or the fact that the engine was just seriously over-revved.
