Default Speedo off

I had 3.23's on my car before I wrecked and without getting into a whole different story, when fixing the car ran into some problems with the rear-end and found a free donor with 2.73's....my problem is now my speedo is off by roughly 13-15mph, my question is what step am I gonna have to take to correct this problem.

You can get your car's pcm reprogrammed to fix the problem. I used HPTuner on my 1998 Z28 after changing the gear ratio.

You can take it to a chevy dealer to have the pcm reprogrammed for around $30.
