so i bought some ebay white face gauges and thought i was big man and installed them myself but then they stopped workin and im too lazy to take them back out. i know all the needles are surely inaccurate at this point. is there anyway to get them accurate again? should i jus get another used set of gauges and get a quality set of white face gauges and let a pro do it or just keep it stock so i dont have to worry about inaccuracy and that other mumbo jumbo
