I have just changed the TB and it is not the source of the issue. So I am still trying to find it.
Well it does two things, the charts above depict the sudden loss of power that lasts not more than one second. It feels as if the supercharger was disengaged or there was no fuel for a second. It occurs while accelerating mildly or during wot. It also happens quite often.
As I do not log everything I was not able to log the situation when it goes to the limp mode. I usually go around 50-70kph (yes it happens when going slow) and it switches probably to what is called a limp mode. I guess that the car disengages the supercharger. What is also does is that it shakes quite badly.
