D5252 Volvo V70 with no power before boost and overall slow

Ok, I have now been out on a test drive and logged some info in VIDA.

MAF reading before starting engine. I assume that the values are way different because the engine isn't running.


This is the reading from the MAF after startup and idling


Driving up a moderate uphill on 3rd gear.



Cruising with cruise control in 80km/h. You see a dip in the MAF desired value and the actual value doesn't follow along. This is because the EGR is blanked off to eliminate that as a cause for the problem.


Cruising with cruise control in 80km/h, and a little uphill.


Cruising with cruise control in 80km/h, and a long uphill.


Flooring it in 4th gear from 60km/h and changing gear to 5th going uphill in a tunnel.


Corrected fuel quantity on idle. The values are almost identical when driving.



Btw; I have tried blocking off the line to the engine mounts, but noticed no difference. Unless it's an internal leak in the valve that controls the mounts.

Also; The accelerator pedal is showing 8% when not touched and the max it reads are about 50%. Is this something to be worried about? My brother had a V70 with the same engine and his measured to 80%. And a friend of mine had a D5 wich i believe has the same pedal, and that measured 6% all the time regardless of how much the pedal was depressed.
