Hello, today we measured mine audi turbo boost and its 1.6 - 1.7 bar! I guess something's wrong. It should be 0.7 bar max. Motor is not chiptuned. Friend of mine told me that maybe maf or map sensor fails to work properly. And fuel mix should be wrong cause of overboost. More air less benzin, so it can harm something. Thnx for your replies !
