CM2250 HIGH coolant and oil Temps

[Paradoc23]

I am in Wyoming. I bought the truck from a guy in North Dakota and that was where the work was done I'm sure. After reading that article I believe that it is a bad De-Mandate. Egr left on but blocked off, oil stays clean only 6500 miles or so, turbo boost 42psi ect.. As mentioned before I do not want to get rid of my vgt turbo and that has been recommended numerous times now and I will be staying a way from those people. I have since removed the egr but need need add the coolant tube and that is gonna happen in the next few days. I need a tuner that takes pride in there work and can help me remotely. I have access to the things I need for the remote tuning so any suggestions. I tried calling mr. hang in GA but time difference they are closed so not sure if he can. Anyone else that you could recommend?
