I pulled the speed sensor out, no change, unplugged it, no change. Tried a new one, no change. Re flashed ecm, no change. At this point I'm thinking it's gotta be the harness from the speed sensor to the ecm or the ecm itself right?

I think turbo speed sensor wire is shielded. Could be bad shield grounding somewhere.
