For a stock SR, he shouldnt be seeing knock like that at idle. Something is really wrong. Stock boost and 30? 15% knock? No good. There is a problem there and it needs to be looked at now. For a more modified car, I would expect the knock to be higher because of a louder valvetrain or large vibrating turbo, but not like this.
