Hey truckguy did u sell ur turbo yet?

Hey fellas new to bigmacktrucks 

I just recently purchased an 06 cxn613 vision  has 900k miles on it but had bottom end redone due to oil pump failure . I know the previous owner and he took cared of the truck very well and pretty much know what was done before he sold it to me. 
 I don't have a slight idea about these trucks specially the engine. He said it's rated to 485hp and not sure on the torque, it's an 13spd and that's about what I know. 
turbo is new, egr valve new, like i mentioned bottom end redone last year, clutch a year old, radiator new last year, Egr valve last year 2019.

can u guys tell me pointers and stuff I should look out for and what I can possibly do about the egr system, maybe a delete or modules or block it??? 
 

much appreciated
