Congrats. I'm new to this as well, as of September 2019. I've changed my fluids, and driven it. Also added some cosmetic items.

Howdy and welcome from AZ.
Hopefully you don't have to worry about anything going wrong.
Did you get the name and address of former owner to ask him any questions about it?

Factory Duramax turbos were well designed, but you can only push them so far. For power levels past about 500 rwhp, it’s time for an upgrade. Turbochargers in the 64-66mm range are good for around 600-700 hp, with 68-75mm turbos being more suited to 700-plus.
