so what hes saying is with those 6.0 turbos with the varible vein you have to drive it like you stole is sometimes to get that carbon build up off the veins on the turbo. Stomp on it :ford:

i sure dont baby it because i did steal it.......lol (good deal),,so the carbon need to be burned off, ok i do drive it hard but dont wanna hurt the tranny, i have pulled 61 psi of boost from what the outlook monitor says more than once.:ford: so should i drive it harder? dont need to pop the egr either, need the head gasket to last, oh and it is a 05. thank for the info please give more if you can

anyways, my truck will do that to occasionally. also another thing, when i start mine in the morning, it rumbles when it fires up, then 5 seconds later, the turbo comes online accompanied with a squeeeeek as the vanes open. LOL

there are a couple of things.

you can try running it hard (which you say you have done)

or you can pull it apart and try and remove the rust off the veins.

if its still under warranty take it to the dealer, they will fix it by either cleaning it or possibly replacing it.
