Quick question for an expert. I picked up a 2000 AMG ML55 instrument cluster. It goes up to 160 mph. I have a 1999 ML 430. I think my cluster goes to 120mpg. Assuming I have a professional install the AMG one and reset to the correct mileage to my ML, will the speed reading be off due to the differences in max speed? (yes, I know it’s a completely stupid project but I’m running out of things to do in my W163).
