I de-tuned it and put my stock air filter back in before it went to the dealer.

When you say 35psi is high for a "Stock" 6.0 are you refering to the stock head bolts or turbo or what exactly?
Because I didn't think that a tuned engine with a high flow exhaust was "stock"

Most 6.0L diesels only produce around 28 psi when stock. The head bolts are the torque to yield type. They get torqued to a specific value and then they are turned more to stretch the head bolt. When you start pumping 35 psi boost into the engine it can stretch the head bolts even more causing the gaskets to go bad and the head itself to warp. So eventually you not only have to replace the head gaskets but the heads also. Now I will not say that every engine will fail in this way but you sure increase the chances of it happening.
