CM870 turbo issue

[Koren]

Continuation of the story) went to Mr. Haggs shop, they checked the software, it was good but not the turbo itself. I bought rebuilt one about a year ago and it went bad. I even send it to them but they said that they tested it and it is a good working turbo. Mr. Hagg said that there is no way they can check it under pressure and that's where you see the problem. Bottom line - do not buy rebuilt turbos. End up installing original from cummins and it has been good since then..
