Evening all, the car in the title with the engine 1.9 jtd 115hp about a month has a significant decline in performance from about 3000 rpm up, at the bottom is a hyena. It just feels a decrease in torque as a net cut.
I did a diagnosis with multiecu+obdlink lx and delphi ds150. No dtc the glow plugs (all new and 4, probably problem on a cable or pipette oxidized).
The car has just been fully serviced fully, the distribution is made at 161000 and it now has 172000. Yesterday I removed the sleeves and intercooler, fully cleaned inside (do not say what is out), clean sleeves, checked and reassembled everything. The egr is already plugged both exhaust manifolds that the intake manifold off is in the ecu and completely closed.
The vgt seems to work correctly, the auction dell actuator is inside and outside of 5 cm.
The data recorded in the third by multiecu are the following:

1. pressure diesel measured 1315, objective 1350 3731 rpm
2. valve is an overboost at 3731 laps 37%
3. the maf measured the minimum 468,7 at 1141 rpm maximum 918,9 to 3731 rpm
4. maf goal, not any given (problem)
5. pressure turbocharger measured 2527mBar to 3731 rpm
6. pressure turbocharger objective 2143mBar to 3731 rpm
7. Amount diesel 50,17 mg/i at 3731 rpm
8. Quantutà diesel total 50,59 mg/i at 3731 rpm

Now the pressure turbocharger is an obvious issue, but the mass of the air lens?? Because it does not return any data nor on multiecu, nor with the delphi ds150?

The boost pressure will be a problem of the map sensor or the geometry of the turbo? (the actuator works)
