The truck is a single rear axle 2006 F-350 lariat Fx4. The turbo went out on me last weekend, so I'm replacing it with an aftermarket turbo. I have a K&N air intake system and 6 inch silverline exhaust. The head studs and egr have not been modified to my knowledge. So here are te coming upgrades from outlaw diesel: Stage I vgt hybrid turbo, SCT livewire tuner with custom tunes, and egr delete kit. Does any one foresee any issues with this setup? Also should i put in the extra G and get a Stage II turbo? I'm pretty sure I would need to upgrade the head studs and gasket and injectors to even be able to take advantage/handle the bigger turbo. Any suggestions?
