So I have not fixed it yet, but I finally know what the problem is:

My alternator.

There is a black/yellow wire that provides power to the speedo sensor and the ABS computer that originates on the alternator. The tuner said my alternator was bad, so they rebuilt it. I guess when they did they messed up something related to that plug...because it is only sending 2.5 volts when it should be sending 12.

The speedo sensor then sends a signal to my speedo...so that is why my speedo is not working and my ABS computer is not working.

So...waiting on the tuner to give me a date to bring in the car so they can fix the alternator.
