Re: wastegate spring related stuff

[Robert Myers <rmyers@wvit.wvnet.edu>]

Correct me if I'm wrong, Glen, but I think the cut-off as described here 
will operate only while there is oil pressure.  When/if the oil pressure 
drops then the fuel pump will be cut off also.  This should also leave 
all other original features of the ECU (other than overboost control) 
intact.  Of course with much higher boost levels there is no guarantee 
that factory mapping will be optimal.

Any volunteers?
