Spartan Question

What does it mean when you switch tunes (210 to 250) and the engine light come on but no codes are present? Is it safe to drive? truck will be making a 400 mile trip tomorrow and want to make sure it will make it home.

Are you checking both Ford Specific and Generic OBDII codes? There wouldn't be a CEL without a code.
