[Vwdiesel] Injector break pressure efficiency?

Maybe there is a correlation with compression ratios... hmm
not with the 1.6 VW though


  I know with Dad's original pu engine, the wrong head gasket gave us 
about 750 psi.  As the rings broke in and "compression" went up.  It 
lost power.  Not only from the extra pumping losses, I had to turn 
the pump WAY up to get enough fuel into it for any real power.  The 
pressure differential between the compression and the injector 
pressure was less so it'd open late and close early.  At least 
that's my guess as to what was happening.
