Competion mode on a 1999 C5, Optional? I have a 1999 C5 and the manual talks about how to turn on the comnpetion mode, but when I try it does not activate. Someone said it was a option in 1999. Is this true? Can the computer be flashed to install it or does it require different ABS type hardware. I have tried holding the traction control button down for 5 to 15 seconds with the car running, stopped, idleing, off, etc, but no competion mode. I auto cross the car and would really like to have this feature.
