Alfa 159 1.9jtdm need overboost fix

[uzepelin1337]

Hello i have a problem with Alfa 159 1.9jtdm,the care came with DPF,EGR,SWIRL FLAPS OFF. And the car gets a overboost like 10-15% when looking the actual and trageted boost.And has no DTC.The guy changed the map sensor,turbo cleaned and tested and vaccum turbo actuator replaced.I was thinking if someone reduce the vacum turbo actuator,or some other solution. Thanks

All readings okay except boost

I can pay for file if price ok. First file and test then pay.

no need to do anything in the map just replace N75 problem will be solved and purchase original part .... if you try to reduce anything in the map you will still have problem i already try it that ... all you have to do is replace n75 and than make sure it is nothing else modified
