Its amazing that you got 26 MPG with the 5.0. From day one, my 5.0 has gotten a steady 21.0 MPG. I do a mix of highway and city driving. If nothing else has changed on your car start checking the basics like tires, plugs, fluid qualities and extra weight. Good luck!

Agreed, especially the Tune.

My MPG increased with the Intake and AED Tune.
