Exhaust pressure- CM871

[Brewster64]

Thanks for the info. I've already changed out both sensors on intake as well as the exhaust pressure sensor, as well as the tubes. The engine is not deleted and has a new ecm programmed to stock 485 cal with updates direct from Cummins. I never let the truck pull when it wanted to run over 40 psi, and made a point of not lugging it when it would heat, shifted down and revved it up to flow air and water. I do think that the bad line was playing havoc with the VGT, Im hoping that it hasn't stressed pistons or head for sure, and if it has we'll be giving the warranty a workout I guess. Going to give it a 4500 mile test drive and see how it does, truck hasn't really run right since I got it, so all I can hope for is improvement at this point. Not feeling the love for it yet, lol. Again, thanks for the info.
