[hauler114]

i have 2 6.0s 1 f350 2006 1 f450 2006 the 450 had injector problems down south and a ford dealer fixed them but they took a laptop and changed the shift timeing & not sure what else but it runs like a rocket the 350 doesnt trying to figure out what they did my dealers up here arent able to get this one out of its own way doesnt spool up like the 450 shifts harder too is there a reflash or update that the guys down south did ? no one up here seems to know thanks much needed help !

a relash on the 450? i think it needs a new one or undo the flash if possible.
