I just followed the video by ipd to install my new boost gauge. I looked into it and so far I've found that it sounds pretty normal for it to read about -20 psi at idle but my real question is that I've heard my 2003 s60 2.4t should be boosting about 8psi stock and it won't go above 2 or 3psi when I accelerate. Does this mean I have a leak? If so, how would I go about finding that leak? I just installed the snabb fresh air intake pipe so I know all those tubes are on snugg.
