Ive got a boost gauge that im almost ready to fit in the car but tonight when the girlfriend was sticking her nose in she dropped it along with its din holder onto the table top it wasn't a big drop but it still made a thud. lol. Thing is the its not plugged in or anything yet but the needle no longer sits on 0 its abit above it. Can she of knackered it or is there a chance when its all plugged in it will sort itself out??
