What was it boosting before? The last time you drove it that it was boosting normally did you do anything out of the ordinary or notice anything out of the ordinary? Can't see how suddenly something would happen to the boost controller to put it down to 10 PSI. Is it smoothly going up to 10PSI? Or really rough?
