Default dyno today

I made dyno to my car today.
Two runs
First is with dual fuel pump set up (stock) and second is with 12v all the time (in diagnostic port FP terminal shorted with B terminal.
First dyno: was 177,9 km @ 4447 RPM / 303 Nm @ 3762
Second dyno: was 184,9 @ 4470 RPM / 314 Nm @ 3758 RPM

So what do you thinking? My fuel pump or fuel ecu is bad?
We make AFR too at high rpms (say 5500-6000) it is rich as pig: 12!!! As in turbo cars...
So looks as it have enough fuel, so why it is stronger with 12 volt at fuel pump all the time? (at road it feel stronger with 12 volts too).
Strange, maybe clogged injectors? (car have 177 000 miles)
Thanks for any suggestions

btw we will do piggiback to it soon. wonder any gains...

From that dyno chart, there doesnt seem to be any fuel problems.. Those lines are perfectly smooth. I wish mine were like that
