But on a serious note i guess. Here's what i would do to it before it even left the driveway. Just for peace of mind (kind of)
If auto-- built ATS stage 6
Step 1 -- rip the cab off
Then install, EGR delete, upgrade the oiling system, new turbo, head gaskets, stud kit, fire rings, new front and rear mains. Then maybe a spartan tuner if you feel like ripping the cab off again.
