Hello everyone and thanks for accepting me into the group. I have a 2010 Mustang GT. It has a 4.6L engine and as far as I know everything is stock. Just picked up a sct x4 tuner and am wondering how to set up everything. Any suggestions as to what settings I can change without hurting the car. I was wanting to build my own tunes and not sure what I can do and not. Looking to get educated.
