I agree that what the tech told you was probably not the best...or any..solution.
The real deal: The 08+ focus uses a mechanical returnless fuel system. This is different from other years. There is no PID for monitoring fuel pressure because of this.

Tom, I know you are aware of this, just thought I'd add it here so that Blivit is aware of my latest little aggravation.
My strategy number is FDGH3F2.H32. Bring up LiveLink and DO NOT connect the X3 to the OBD port. You will be asked to enter your strategy number (FDGH3F2). The list of PIDs that is displayed is different then the list you get when the X3 is plugged into the ODB port. When it is plugged in to the OBD port some important little items like, "pressure drop across injectors" that is displayed when unplugged is no longer listed.
I sent that info to SCT support and the answer was:
"PID's that show when the device is not plugged in are general/default PIDS, and are not necessarily available to datalog. This would be why you’re experiencing the issues you are. The only recommendation I have for you is you could possibly have the vehicle re-flashed by Ford for a newer strategy and that could possibly provide more/proper PIDS to datalog."
Really, I'm supposed to hope that re-flashing my ECU will solve it?
