I removed the boost controller and ran the car again an the boost was dropping from 7 to 5. I suspected the boost gauge and removed the panel to find the line disconnected. It must have been hanging by a thread and fallen off when I pulled the panel. I reatteched the line and the boost controller. The next drive should an intial 8psi and a drop to just above 7psi where it would stay planted. I guess the small spike may be a characteristic of the controller. Any opinions? Thanks, Todd
