Be sure you know what the manufacturer's rating
pressure and your real fuel rail pressure are. You
may have some things to compensate for before
going and changing the value. There are some good
spreadsheets out there for it. The rating pressure
may be hard to dig up (or hard to get one single
straight answer; like the Ford SVO 30s, Ford says
40PSI but have seen many folks saying 3 bar (42ish).
Double check.
