If the FICM has been updated then Yes Jack you are correct. there are a couple of posts here about FICM and reflashing that Bill can do. so the OP could read those... it was a real MPG killer. most people saw a couple MPG drop after the update.
Also should read the PSD forums about replacing the head studs. the original ones are prone to stretching and causing head gasket leaks.... I tell ya it would be nice to have a one piece hood on the ford like on my 4700 International.. made doing the head gaskets real easy on that truck
