I’ve got a 2009 F-150 lariat with the 5.4. V8. Two questions. Anyone have a clue why the dealership “stealership” would charge me 550 to install a pcm? I’ve seen videos of the 2008 and it’s only a few bolts and connections and then driving it to set up the pcm. Am I missing something? Also where is the best place to buy a new pcm?
