Nice! EGR, DPF, turbo back free flow exhaust and a good conservative engine and tranny tune, the truck would be even more of a beast than it is now........more fuel efficient if you can keep your foot outta it. And still very reliable!
The key to longevity in that engine is the oil and coolant. Both must be high quality and changed often. Rotella T6 has been my go to oil since it came out for 7.3, 6.0, nasty 6.4 POS and the 6.7.
Good thing ya don't have that POS 6.4. Something goes wrong mechanically, it's pretty much a throw away engine. Dumb design!
