New Truck - X15 Advice

[Camstyn]

So I ended up buying a new Pete with the 565/2050 Performance series. The Paccar MX has been in the shop with CEL issues almost every day, the new truck couldn’t come soon enough. I expect I’ll have it on the road next week some time, I’ll post fuel economy results once I get it sorted.

Any advice for this engine, other than don’t lug it or excessive idling? Has anyone tinkered with them much yet?
