Is there any way to tell if my used ST has a tune on it or if it's stock tune? It came with a few mods but id like to get a Cobb accessport and I read that if you try to install a tune over anything but stock or Cobb it can mess things up. It had an cold air intake, short shifter adapter, shifter bushings, exhaust was stock, intercooler looks stock. Also read if it is always telling you to shift than it's probably stock. It always alerts to shift at like 2k or 2100k rpms. Thanks in advance
