URQ fuel pressure numbers

Thanks to Smitty, Ameer, & Phil for the quick responses.
The readings I got from my car were;
        warm (not hot, set 1.5 hours)   system-33 psi  2.27bar
        fully warm                      system-49 psi  3.41bar (after app. 3 
min.)
        fully warm                      control -89 psi  6.14bar
        residual (20 min.)              system-35 psi  2.41bar
Are those close enough or is there some tweaking to be done.
The frequency valve will not stabilize. Two degrees either way on the 3mm 
allen screw sends it to 63.1 or 4.8. If I dial it into 49.1 it will stay 
there until driven and then migrate to one end or the other. The crackle on 
decel at the exhaust either gets worse or goes away, indicating mixture 
problem?? 
FPR resistance is spot on, and O2 sensor is new. Car sometimes runs perfect, 
other times feels that it leans out and/or goes rich. I have wired the FV 
meter to the interior, and monitor it regularly.
I'm sooooo close. It appears that some sensor isn't performing to spec. Temp 
sensor is also spot on for resistance values.
Any ideas?
