I don't have a tuner, I have only had my car for a little over a month or so, and I am just trying to get it to run as fast as it was stock. One of my sticking points is that the computer seems to be dumping boost on me all the time because of another issue. But I am just wondering how the valve could cause a lower than normal boost value. After I started thinking about it just now I could see if the valve is not seating properly and allowing boost to open the valve until it into equilibrium with the spring force trying to close the valve. Would this be a correct assumption?
