I had the same code pop up after my turbo build. The forward facing turbo headers caused me to relocate my chassis ground from the passenger side of the block down to the starter bolt and mount a bit lower on the frame of the car. Well some how I managed to bolt it to the frame with a heat shield between the cable and the car. The car ran and drove a bit before it started acting weird. Then the battery seemed dead, was throwing a P0606 code, and going into limp mode. The shop found and fixed the issue and now all is well. Hope its that simple.
