Maybe. I normally would expect a DTC (trouble code) set, yes.
But the trouble code could be a code set in service 7 (trouble codes from last drive) and not yet in service 3. I don't know if your tester can read both services.
Also, I don't know what the exact limit is (30%, or maybe 35%). And then the next question is how long (milli seconds, seconds) must the Long term fuel trim be at the limit before the code is set. So, it's possible that you don't get a DTC yet.

As GVK already answered, the manifold pressure is in your data list and called "Inlet manifold Absolule pressure".

I would change the fuel filter for an original Ford one. That shouldn't cost that much.
Check whether it's dirty or not and then try again.
