GXP Speedomeyer problems

I have a 2008 G6 GXP with the 3.6 in it. The gauge reads almost always double the actual speed of the vehicle. I plugged in a scan tool and it shows the correct speed. But the gauge pack shows different. Already tried a new gauge pack any ideas?

Sorry to be no help, but I cannot help thinking this would be a great time to make a video of your "modified G6" pegged at 140mph....

That said, do you have your car set for KPH rather than MPH? I think it is the display units setting in the DIC. English or Metric
