2011 FX4 speedometer malfunction
my speedometer is stuck at around 40 at idle and goes up to 120 when going 60. It seems double over 20 mph. I found a way to access a service menu and get a digital readout of mph which works correctly. What could be causing this

Speedo correction is a function of the Superchips unit. Sounds like a scaling factor is off in the program someplace. If you got it from a dealer take it back and have them fix it. It couldn't pass an inspection with that issue. If you got it from a private party... you're on your own.

Contact super chips they might be able to help and see if there the problem or not then start from there. All I know is if you go to the dealer most of them won't touch it knowing its been tuned tho.

Just an update, the mechanic had to replace the whole instrument cluster. Its all installed and they are bringing it to Ford in the AM to get it calibrated. Been without the truck a week.

Ford still has the truck. There is some type of drain on the battery now. They're saying a faulty sensor. Going on about 10 days now. I don't even barely remember what the truck looks like. Only had it for 2 days before it went into the shop.
