re: loss of low down torque 1.9 tdi quattro 130

[tamtom]

any help much appreciated.
many thanks to Sailo (Jakob) from the forum for doing a diagnostics log for me.


i've noticed a major power loss low down especially torque from take off.
since the power loss i've cleaned the vanes in the turbo, removed the egr (egr delete), de cat and a front mount intercooler.
none of the mods made any difference to the power.
there was two vaccum pipes which were going to the egr valve which i have now blanked off.
The car does seem to react better when cold but still not 100% of what it used to be.
there must be some explanation to why i have lost so much power.
I have installed a boost gauge to check what boost im running at, the maximum boost is above 20psi around 25-30 i would say, its hard to say as it go's off the scale.
i have a data log from the MAF and Boost sensor. 2 logs of each i believe.
the logs were done on flat ground motorway from 3k to redline.

Any help is much appreciated.
