Good afternoon to all...
I have a problem with the turbo pressure...
Practically I have little pressure under 2000 rpm (about 0.5 bar), then the above is all ok...
As you may be able to recover this annoying hole?
It could be a problem of variable geometry?
I did the test also with the vacuum direct to the actuator, and things do not change...
Ps. Turbo gt1852 in avional...
Thanks to who will answer...
hello can you tell us a little bit and email the file ori and modOriginally Written by mrpaccio
I agree even if I will not be able to see the files, however, without a better explanation nobody will be able to help you
hello, if you have mounted a turbo impeller is changed, you can have this problem you have low revs, happened to me and with a turbo brought in by the customer with the impeller in avional changed in the palette, and the bottom was completely dead, then the top would pull so much, but honestly, for a turn in the road normally, I don't see the need, another thing to check is the egr, on the contrary chiudila with a strip, then the other thing, that the map you have on your car? ori or modified? if it is changed who the made and on which criteria it is based?.

have you tried to "tighten" the geometry?
obviously with the turbo the more will increase the turbo-lag you should correct the map and logically close the egr valve
This problem here I also reflected with the golf 5 105cv after you have replaced the turbine with a plus at low rpm sobbed and hold it and as soon as he gets to 3000 rpm it pushes cou a nice ball of smoke I can not understand if it is manzanza naphtha; pressure turbine or if it could be the sensor mass air
