Your car should be -10 at idle, if you're idling at the proper RPM. It should reach 9 to 9.5 pounds of boost with a mildly modified intake this time of year with cold air. If your idle is fine, I'd be considering replacing the bypass valve. I'm still unclear on something. You stated earlier, that "when I unhook it, I go from 2 pounds of boost to 7". At what RPM level? Driving, or not? I need some specifics here to properly troublshoot this.
