Freelander 1 Td4 Live data on sluggish drive- Any ideas?

Hello All,
Just had the data read out and was wondering if anyone of you would have some advice on what the problem might be. The car's driving sluggish again and fuel consumption went up to 9.2l/100km or 30.70mpg if I calculated it correctly on mixed. If I go through it looks if there might be some issue with HP pump, but not sure. Sometimes the values were gone.
I put it together in the pdf attached like the one Andy did a while back to have a comparison, first file (test-pics). The second one is from a live.log.

Had another run today and am wondering if the MAF has issues again, but the values look a bit odd. I would have thought that if the speed is kind of steady that the bits react the same way or is that not the case? Seem to be swaying, i.e. at 69kph => 75 MPa railpressure and then on 78pkh => 63 MPa and so on. When I remember it correctly old values it was constantly going up with increasing speed.

Same on the MAF side. It seems also swaying. Would have expected to see values close to or above the requested values, but usually not. Had it changed end 2018 for a genuine Bosch one. Will unplug and test, but the values look also not constant to me. Would the renewal of the air filter make any difference maybe or could it have an influence on the MAF?
