Thank you very much. This was very enlightening! (And reassuring that there isn't some major electronic problem with that car!)
I will eventually figure out whether I go with the ways around the turbo shot-off that are described there. For now I will simply take the plate back out and have a car with turbo boost again. 
Anyone with a 601/2/3 on here who runs it on VO or biodiesel? Do you find that the intake gets crudded up less on biofuels?
