I hate that my 2008 Escalade doesn't have the instant MPG "gauge" since my 2007 SRX has it and my old 2005, 2006, and 2007 STS' all had it. I want to change out the cluster with one from a newer truck that has it and I'll just get the mileage programmed to match my truck. I thought I remembered seeing a thread somewhere about it but I can't find it now. What year did the instant MPG start in the Escalade? If the cluster shows the ambient temperature and compass (which appears to be 09-14) is that the one that will have the instant MPG?
