when building my FCD, i asked a freind if he could use a bicyle pump to give me a constant pressure. I had the pump hooked up to the boost senor and my greddy gauge. When i asked him to start pumping he did and when i got to my gauge it was at 2 bar. So i turned off the car and the needle fell to the right instead of the left and now it doesn't move at all when a drive the car. i have a picture but i dont know how to put it on my post. does anyone have any ideas on what i could do to get my gauge back to normal.
