You just need to log the desired and commanded fuel pressure PID's. That will show you how well the system is keeping up with the fuel demands.

I no longer monitor the forum, please either post your question or create a support ticket.
OK I'm pretty new at this too, but I'll try and walk through what I know.
Open scan tool, plug into truck. Click the green connect to vehicle button on the top left.
Now click on the PIDs tab. Click the clear PID selection icon. Now just below the connect/disconnect from vehicle buttons is an icon with a green check mark, click that or just press shift and F2. Click the supported box to get rid of the ones you can't monitor anyway. Then you can select the PIDs you want to monitor. The caption for actual fuel pressure is FRPACT and the one for desired is FRPDES
