[Retro]

With my duramax it was giving egr codes so they did the delete on it, still no boost, checked out a couple of other sensers (dont remember what ones) the last resort was the turbo, its no small job on a duramax. But it was the culprit. The vanes were siezed up. Funny it was giving egr fault codes I thought. A very reputable shop did the work. Had to lift the cab to get the exhaust bolts out to remove the turbo. It was a job I wasnt at all interested in tackling myself!!
