Welll long story short
Truck got an inframe, mechanic poked hole in air to air. Diesel spec tuned and then removed an replaced with another also egr delete. Turbo hung up 3 times on a test at mechanics but with key on and truck running and then shutting off truck it reset back to what looked normal with no restriction.
Truck has high(in my mind) egt. Running down the road it’s around 800 empty and maybe 900 when pulling a load. If you get into it hard the egt will actually drop about 50 degrees which is wierd? So does this sound like symptoms of a bad vgt turbo? And should we replace the turbo with the like or go fixed vane and retune? Also is it best to just pay Cummins prices for the turbo? Truck also has a bit of a surging idle. So we suspect meter solenoid but not sure how to test and I think they are $750 a pice? And do the timing solenoids need to be changed as well? Thanks
