What did you change to not go into fail safe mode?
I'm having the exact same problem. How do you remedy it?
I have a 2006 Mustang gt that keeps going into fail safe mode at WOT also the speedometer is not accurate, I think they are connected. The vehicle also has a TR6060 which isn't factory. Other mods...
