    Need Speedo Help

    I recently re-did my cluster- New si-board- Painted needles-did not remove them- replaced odo gears. Now everything is perfect except when i'm going about 55 my speedometer says i'm going 75 what could have changed i never removed the needles and the speedo was the only thing that worked before the rebuild.

    on the back of the speedo there is a screw head looking thing. From what I understand that varies the resistance of the speedo head. It's used for tuning it at the factory. Perhaps you inadverdantly moved it.
