I need some input as my XC90 is driving me crazy at the moment.

I still get ECM-135F MAF Signal too high and the car is running like s..t, hardly accelerating at all.
At around 1500 rpm the car is shaking but then reving a little bit higher.

What happended:
Due to my own fault the timing belt jumped (did not adjust the v-belt correctly...).
This was corrected, compression tested OK. Timing is right.

I still get the MAF Signal failure and checked/tried the following:
- swirl flaps seem fine
- MAF already changed and seems to work fine in VIDA, reading "correct" values
- I found a little air leak in the turbo rail and replaced the rail without any changes at all
- turbo system compression tested, everything seems fine
- replaced MAP
- I cleaned the EGR and checked the butterfly valve
- DPF regenerated by VIDA
- turbo control was also tested and is running fine

Any ideas how to proceed now? I am completely lost....
