Speedo still off

Replaced the speedo gear today. It went from indicating 10% slow at all speeds to 3mph fast at all speeds.

33x12.5x15 tires, 3.73 gears. Installed a 31 and pulled out a 39. Every chart I've looked at verifies I need a 31 gear.

Any advice or suggestions?

You can get it close, but honestly if you want dead on...get a smart phone with GPS and download a MPH app. I use "Car home Ultra" personally and rely on it instead of my built in speedo.

In all my years of driving I have never had a speedo that was 100% accurate. Ask any mechanic.

You might measure the diameter of your tires. Just because they say 33, doesn't mean they actually measure out to that.

X2...I had to install one also for my super short SYE (no speedo gear). Very nice unit.
