Turbo issue??

[Scoot5869]

Hello and TIA. 2010 cm871 500hp
So I finally have been able to run this new truck for a couple days had to replace some lines and damper that was a fun project. Anyway ran fine yesterday with no issue water temp seemed a little high to me ran at 200 a lot but could be cab gauge. Oil temp was 210-230 only 230 when I was pulling steep grade temp also rose to 220-225. That was only concern I saw.

Today it ran fine till this last load. Now it’s windy here and finally getting warm 56. Truck temps were running fine in the morning but this load it seemed like water was staying consistently at 210 fan was on and off a lot however I was going into the wind too.

My boost never goes over 39psi when at full lull and runs low maybe 15-20 at normal pull.
Was driving and saw engine light come on and felt truck lose some power not a lot but noticeable. Saw boost was at zero. Sounded like turbo was still working too but the inhit throttle it wasn’t. At this time two things I noticed was that cruise didn’t work little center said reals brake for cruise. I was driving so brakes weren’t set. The other thing was the jakes didn’t work.

And I’m waiting on my insight so I can’t hook it up so I’m at mercy of dealership
Unless the gods here can help.
Turbo was a reman to saw it was made in Mexico in 2016
