Buying a used 2018 X15

[Camstyn]

It’s a 2018 IHC LT625, 450hp efficiency. It has 6000 hours and 200k miles. I’m not new to X15’s, this truck is replacing my 2020 Pete with 565 Performance. I’ve kept up on 15000mi oil changes with 15-40, annual EGR tuneups and did the overhead at 300k mi (it was good, jakes and exh valves were just slightly tight). This truck was always babied by me, run at 1500-1800rpm and seldom exceeded 20psi boost. No excessive idle time, 7300h and 340k miles.

I don’t know the maintenance or driver history of this truck, but it is freshly serviced. What would you suggest doing immediately besides an EGR tuneup and maybe run the overhead? The spec of the truck should be a money maker, 16spd direct drive autoshit with 2.64 rears so same final drive as my Pete with 18spd/3.73’s. I’ll manually control the transmission to keep the RPM’s up and the boost down.
