Default Fuel Gauge Runs Backwards

I had my 2003 Silverado 2500 tuned with a LS edit programmer and now the fuel gauge reads backwards. Meaning that when the fuel tank is full in reads empty and when empty it reads full. Is there something that was missed in the programming? Or just a freak deal that the computer messed up and need to be replaced?

Sounds like they threw a tune in not from your vehicle. In 2004+ Calibrations GM flipped the AD counts for the fuel gauge. Just have your tuner flip the table.
