I called edge and hypertech about a month ago and edge said they don't have one for the F250/350 5.4 yet and the F150 5.4 won't work on it because the f250/350 have a 5 speed auto and the 150 only has a 4 speed auto. Hypertech said it may work but you won't beable to adjust tranny set points. Edge also said they were working on one for the F250/350 bt it wasn't out yet.
