I bought a sixxer of and idiot.He put gauge covers on,and none of them are accurate at all! I called him and he said he pulled the needles off to install the LED covers.I'm a mechanic,and usually have things calibrated correctly by a pro in thier field. Is this an easy fix/problem? I'm sure the needles have a start/stop pin that goes to gauge,but will I ever get it "spot-on"???
