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.
Cheers,

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

Very good!I like it! I like it! One hot summer day a fox was walking through an orchard wow power leveling. He stopped before a bunch of grapeswow powerleveling. They were ripe and juicy. "I'm just feeling thirsty wow pl," he thought. So he backed up a few paces wow power leveling, got a running start, jumped up wow powerleveling, but could not reach the grapes. He walked back. One, two, three, he jumped up again ,but still, he missed the wow power leveling[/url] grapes. The fox tried again and again, but never succeeded. At last he decided to give it up. He walked away with his nose in the air, and said“I am sure they are sour.”
:blahblah:

He must have quoted a spammer's post that was removed.
