ok i got a 04 f450 which i hate but i use it daily to tow my landscape trailer its constantly breaking down but i need to get it runnin better so i can sell it. heres my problem it keeps barkin the turbo on me after about 2250 rpms maybee 3000 on accel unless im just cruising i had taken the turbo apart and found the unison ring cracked i replaced it cleaned teh housing real well it was pitted up and flakeing i got it cleaned well and everythgin put back togheralso had found the exhaust manifold gaskets were leaking got those all replaced. also replaced teh vgt solonoid. checked the egr valve and looked decent but went ahead and cleaned it off and put it back it ran a lil better but still barkin like crazy so i unplugged the egr valve and it runs a hell of a lot better but still barkin and dosent pour black smoke as bad as it was with the egr plugged it but it only smikes while the turbo is barking this is my main lawn truck and need it fixed asap. i told my buisness partner this is what u get when u buy a ford but its been good to us for years till this plus it also has injector morning sickness runs rough till it warms up
this is all i can think of
