]I have a 01 Sierra, it has a Escalade cluster already swapped in. I really want a way to view my instant mpg. Im not sure if i can do this with a stock cluster ng, it seems 05+ gauges don't show instant mpg. However it seems this seems to be true for the 03/04 trucks that had the updated dash/gauges anyway? Is any 2001 capable of showing MPG with any gauge? I thought maybe it would with a <05 esky cluster, and i just had a newer one. Or if a 01 isn't capable, and I have to buy a scan gauge or something. The only thing my current escalade cluster shows is mileage, and trip.
