Sorry for waisting bandwidth with this but I am sure of that these figures
the magazines quotes don't come from the Bosch book.
The Bosch book says that their systems use between 350 and 1600 bar and
doesn't say anything wich car make uses what pressure.
The magazines wich by the way are very respectable magazines here in
Europe says what each car model uses. And this have happened a lot of
times and with a few months apart. For instance the VW was quoted using
2050 bar....and I have seen other makes with pressures at 800 bar, 1280
bar, 1400 bar....It just seems strange that an error like this would exist
in the magazines for several months and in a lot of magazines. I really
think that these magz have some sort of error correction routines and that
errors like that would not slip through printing in such a long time
period.

Sorry but I have not changed my mind :)
