We understand your situation. We have a 2005 F350. Replaced two OEM EGR coolers and a FICM before we really knew the issues with the 6.0. When the first EGR went out it was at the dealer for almost 3 weeks before they figured it out. We did our own research and told them where to look.
Going on two years ago we did a full Level 2 Bulletproof (at North Texas Diesel-we wouldn't trust a dealer to know anything about Bulletproof parts) AND added Bulletproof FICM, water pump, bypass oil filtration, full Bulletproof cooling upgrades, new head studs, oil cooler, fan clutch, all new injectors, new head gasket, and replaced plastic intercooler pipe with Bulletproof metal pipe.
My suggestion is to replace more of your factory and other aftermarket parts with Bulletproof parts and your truck will be solid.
We have done three long distance trips since the Bulletproof work and some local trips. The truck runs smooth and we don't worry about it anymore. It runs quite a bit cooler than before the Bulletproof as well. Would we like to get a newer truck, sure but this one is doing all that we ask of it. It now has 170K miles. We add Archoil diesel additive at every fill up and Archoil oil additive at every oil change.
Was the Bulletproof expensive, yes it was but it was still cheaper than a used truck and that is what was important to us because we only pay cash for vehicles.
The OEM 6.0 had a lot of problems but Bulletproof has the solution.
