Thanks to @wsteele I checked for a calibration available for my FPCM in my 2013. I have one available but cannot see the FPCM with my Tech2 however I didn't look in module setup in the control section.

I didn't realize you had a 2013 (just forgot to look at your sig). You should be able to see the FPCM in the diagnostics section with the Tech 2, see all the stuff Ken and James have been talking about FP, Trim, etc., realtime. The navigation to get to those pages are contained in the post above by Tom @gooffeyguy. If you page through just as he shows, you should be able to see the FPCM section.

That's the thing... I saw that post and went looking. No Love! Not there!
I will check again tonight...

That is very strange indeed. You definitely have a Fuel Pump Control Module or you wouldn't have a listing in the controllers window on the TIS2web search results page for your VIN and no calibrations listed for it.

Found it! They say “with trailer brake control” so I never selected it.
Here is my pressure at idle.

Out of curiosity, how many miles on your rig?

When I was looking at part numbers there are FPCM’s that are no trailer brake control and others with TBC. I suspect they had some pins available and some spare processor cycles, so put that option in that location.

Does your truck have TBC?

Definitely not trying to hijack my own thread, but given that the system doesn't even see the FPCM in 2007, I wonder if an Integrated Trailer Brake Controller option was even offered in the 2007's?
