Turbo question
 

Hi

It seems that my CLS is having over boost. Any idea if this is normal?
The boost actual boost pressure is not follwowig the "norm". This test has been done on a Bosch KTS tester.

The reason for checkin this parameter is that I'm having a problem with gear change, it hard from 1st to 2 nd and slip from 2nd to 3rd.
Car has done 45 tkm and I have got a new gear box and new converter but the symptoms are the same. Of course it has been throug several gear adaptations but no difference.

I'm suspecting the uneven boost pressure casuing confusion on the torque out and mismatching with gear box parameters when changing.

Any ideas are welcome what could be.

Thanks
