Just to clarify, the higher the vacuum the further the FPR opens to allow more fuel correct?

And I believe we are saying the same, more vacuum opens the FPR further and decreases fuel pressure in the rail
~20"Hg / idle opens the FPR and decreases fuel pressure = less fuel
0"Hg/atmosphere / WOT closes FPR and allows more fuel pressue = more fuel
Positive pressure / boost allows even more fuel by closing the FPR further increasing the rail pressureLast edited by whodwho; 09-03-2011, 06:54 AM.
