I had remembered reading about a guy working for ATS swapping a 6.7 cummins into an 07 F250 and having twin turbos. He had a 62mm over S475 turbo. Here is the link to one of the magazine articles that covered it. Hope it helps...
I found a link for a $30 dollar usb scan tool supposedly capable of reading CAN bus data and is compatible with many different scan programs. Not sure if it will read diesels, I've been told by a local mechanic friend that there is a major difference...
Great project. Wish I had time / space to try something like this.
What are you using to read/scan the CAN bus data, and do you have any links on CAN bus data. I have an 07 250 that I'm considering doing a swap on as my 6.uh-oh is beginning to have signs of dying.
