Trying to find cause of this on a friend´s car...

We are tuning his rs4, and have done the linearization runs with fixed wgdc, but when tring to get PID working we were having a hard time and alot timing pull. We dial timing back but still having timing pull, so he did another runs with fixed wgdc 70% to compare with previouse run to see whats going on.

the boost is slower to build(although it as not been constant) and is lower by about 0.2 bar

We are having alot tming pull although it is runing less boost

we fixed some leaks at hoses, replaced DV´s as they were not sealing well, but without improvements.


wd is not on logs but fuel is following requested just fine...

Any ideas?

logs don´t have alot variables cause he as a busy k-line, will have to run a direct line...
logs from 60% 70% ok and 70% with lower boost and tming pull
