Speedometer error

[jeffnoel]

I recently had to replace my instrument cluster because the tach in my old cluster died. My problem is that the new speedo reads about 10mph fast (verified by GPS) when the speedo reads 55 GPS reads 45. Is there an adjustment screw on the speedo used to calibrate? burn_out

Not a screw, but you can adjust the tension of the spring used to create resistance inside the speedo.

I wouldn't try it myself, though. Go to a speedo shop and have it calibrated.
