Just received my Edge today and the instructions say to return your trucks ECM to stock. I have no idea if the previous owner has left a program on my truck or not. The gauges he installed points towards the idea that he did have a tune on it, anyway I can know for sure? If so, whats the best way to go about this? Or is it really not a huge issue... it says potentially ECM or engine damage can result... last thing I need right now.
