Update.... egr replacement and vacuum leak repair did not fix the overboost problem. Dealer is stumped and a Ford engineer is on the way to figure this out. Bummer. I love this truck, just want it to work.
Glad they are getting a engineer on it. I am sure they will figure it out. For the guys that know these trucks, in my opinion they are not all that complicated.
If they come back that the motor is destroyed by eating the screw, demand(nicely) a buyback and replacement. Seems like others are getting that with a bit of a push.
