I swapped my gauge faces out not to long ago and I noticed that my speedometer was really off. Is there a way to reset the gauge cluster to factory specifications?

We dont have any of those electric speed signs or anything around here, so do you think my tuner can possibly fix it?

 

i know hptuners will say your speed. you could have your gauge face off and have a passenger move the needle. just set the cruise control and stay on a flat road. otherwise you have to send it off to be recalibrated.
