How do folks, long time no yak. I found a place that can print me up some factory instrument panel overlays for my GMT800 2000 Silverado, only instead of a 100MPH speedo they can print me up one for a 160MPH speedo. They can actually do me one for anything from 100 to 180MPH. Question, can I use EFI Live to correct the speedometer for the new overlay, while at the same time keeping the odometer correct? Or will I need to look into getting the instrument cluster itself altered? If EFI Live can do it, I'd appreciate any tips and if the cluster itself has to be dealt with, anyone know how? Thanks.
