so i went to sand off the ugly green on the back of my cluster gauges and i actually took the needles off my rpm and speedometer, my speedometer seems to be fine it just lags going from 20 down to 0 but my rpm gauge with the car off is at 1k i can't seem to get it to work right it laggs horribly granted its not that important seeing as i have an automatic but the fact its messed up is going to bother the hell out of me.... please help
