As you know I changed my IC with bigger and I got a big lag. After a remapp it was a little bit better but I wasn't sattysfied. Now I decided to put back the old original Fabia RS .IC And it's the same. Car pulls from 3000 rpm. I don't know what it is. I can hear turbo start sppining at 1500rpm but nothings happens. I checked the pressure sensor and I think it's ok. Even cleaned and closed the EGR valve. On the dyno it's claear that I lost the torque. The torque rise like power. I have 158 HP on 3930 rpm and 295NM at 3700. Before torque was 340NM an 2200 rpm. I have no leak. What should i check next???

do you have access to VAG COM to do some logging of the boost?

 

[pikzibner]

My friend have vag com. I'll try to do some check with him

vac leak or sticky vanes sounds favourite, like eventually the revs catch up to the position of the vanes and you have boost again

THANKS GOD problem solved. The little part of damper half broke where is connected pipe from solenoid valve block to damper. And there was no vacuum. I started checking all pipes and pulled hard this pipe and it broke. When I sealed the pipe car started to pull from 2000 rpm . Noe I have to buy new damper (thank god it's not expensive).



1 stupid thing i did. As everybody told me it could be MAF sensor, i took it out and cleaned it with alcohol and f.cked it up. So I also have to buy new MAF.
I tried to drive the car with MAF from TOURAN 2.0TDI and car GOES LIKE HELL. Now I can sleep. Greets and thanks to all.
