Any wrench or check engine lights? What are the codes that are stored? Fuel filters?

Get another dealer with a certified tech. Ask for a ride along with the flight data recorder.

You will need to read the codes. You could try places like Autozone and see what it indicates. They can usually read the generic codes at least.

If you cannot tell then you will have to take it into Ford and have it read.

Are you still under warranty?

I am thinking since you have no check engine light, or wrench light or whatever, it can't be in limp mode, but I could be wrong. But I'm pretty sure that if the engine reduces power, there would be a light or notification.

Are you tuned?
