Speedo Question
I have 3:73 gears in my car and the shop used HP Tuners to calibrate. I noticed today that when I set the cruise control, the speed on the DIC doesn't match the speed on the gauge.
Any clues how to fix?

Not sure if there is an easy fix.
On both our 2006 and now our 2009, about 95% of the time the DIC Cruise Control speed would show 1 mph higher than the HUD speed. The analog needle agreed with the DIC.

Not very helpful info other than they don't match. Telling us what the difference is would be helpful.
