then,I lowered the 5% of the map geometry(vgt) and the problem is significantly lowered,having opened the palette of the geometry of the turbine definitely thanks and the car is less annoying to drive,more progressive,and certainly I have had a small decline but I can also afford to raise a little more pressure since it's not in the film as the first but much more stable
Have you lowered on the whole map or only at partial loads?
to try I lowered across the whole map,the peak remains but is less annoying,probably still lowering it a bit would be even less, but then it would be too open and faticherebbe as well to go in the pressure
Spring in the wastegate that flickers �,
This explains why the pressure is unstable. I had the same problem on a subaru impreza reprogram very little. I solved it by adjusting the spring preload
*rescheduled from little
it is a problem on many of the 159, I don't think is at all a problem with the wastegate gives a piccata with no pair x, then lower the pressure and rise of torqueOriginally Written by cronoprima
it is,in fact,
considering that this is a very fair response

Hello all, I am new to this forum and I'm owner of an Alfa Romeo 2.4 JTDM with 200 hp. I am writing because I too had a similar problem as the drive, particularly during the period of scorching hot weather, she started to give me a series of problems rather obnoxious. As the first skirmish has begun, despite the turbo was pressure, not to have compression, then the pressure of the turbo has started to vary between maximum and minimum peaks a few times also seghettando without providing power to the motor, and only after you have turned on the malfunction indicator light engine eliminating almost completely the efficiency of the turbocharger. I did replace the DPF with a pipe removal, close with flanges l egr and reprogrammed the ecu; in the course of the operation was to clean the throttle body, the egr valve itself and the first part of the inlet conduit that were in very bad conditions. Now the car goes better but it is still at the top because I think it needed a more thorough cleaning of the suction and, as it says in the mechanic of the "geometry" of the turbo ( which failed to explain the mode in a comprehensive way, or rather clear). The power of the machine is good, if the high gears, it asks for power, the turbine has some seghettamento, the power consumption is not changed at an all time high in the city and parks on the highway ( with 80 euro of diesel I have travelled 980 km at a constant speed of 130/140 km / h) and then better than before I would say; I keep hearing the so-called "whistle" similar to the breath of the cheetah (who has always done since the purchase of 2,000 km and it now has 62.000) but the mechanic claims that from his inspection of the swirl is not damaged. You recommended something else? Thanks and sorry if I have bored. Good day to all
