Recently put a 5.3 into a 04 Colorado using a 03 Tahoe dbw computer. Everything works like its suppose to except for the odometer. It is counting super fast. Or I'm getting extremely good mileage. 1100 on a 19g tank of fuel and I still have 1/8th left. The speedo matches the scanner which matches my speedo app on my phone which matches my 2016 Ram 2500. Is there a way to slow the count down?
