Hello
2013 320d auto
Stage 2 DPF off EGR off, chain done recently, swirl flaps removed 8 clean intake manifold.
So, i’ve been trying to solve this problem here.
The best way i can explain it is that lately my car has felt sluggish.
It’s like i have to push the pedal more when accelerating for something to happen, wheres before i just tapped the pedal and the car jumped right away it felt very lively. With this sluggishness i also have much higher fuel consumption, even when cruising on the motorway.
Also sometimes it feel like the car shifs down a gear to get the power needed in slow speeds. And sometimes holds gear longer when shifting up.
No leaking injectors, no error codes nothing.
I looked into MAF and when reading with Scan tool it jumped crazy from 5 g/sec to 25g/sec just up and down. Reading with ISTA shows 45-50 kg/h. This is on idle. So, swapped over MAF from friends (in his it reads normal) same car, still my MAF readings jump up and down. So i guess maybe problem somewhere else. Can it be a boost leak? At WOT the boost seams to hold itself. But im no pro mechanic maybe im missing something. I’ll attach some pictures.
Some pics show crusing at 50 kmh, some show WOT. MAF, MAP and boost readings are there. As i said im no pro so if someone could help me out i can take other values of other sensor.

Thanks!
