: bad bypass valve?

8th March 2009, 01:09 PM
hey everyone, i have a 2001 9-3 SE Hot.
lately i have noticed that boost has been alittle low and and somtimes when i get on it it will build to half yellow bar and then go to the end of yellow/red so i was thinking it could be the bypass valve or the waist gate but am not sure. has anyone else had this problem, and what was done to fix it?
