[QUOTE="dseitler, post: 1006142, member: 14112"] The 5V reference voltage is there. With the key on not running I would think it would show barometric pressure. It shows 2psi. I don't know if that's normal. While driving the back pressure is all over the place. If I clear the code I can get 25lbs of boost and that's all. It will throw the code within a mile. Checked the connector it looks new. Pins are not bent. Put soapy water on all boost air hoses under load. Exhaust side shows not soot marks. Still looking Sent from my iPad using Tapatalk [/QUOTE]
