I'll try my best to explain this clearly lol I'm still running standard Boost by the way... Basically on low boost the car is pulling/boosting fine, But on High boost just as you get past the point .6 bar that low boost is set to i think, I can hear a hissing and it doesn't boost any higher then what it would on low boost, I'm going to put my standard recirculation valve on and see if it's cure's it, but most people are saying it's probably my actuator, But to me it sounds more like it's just leaking from the BOV Has anyone else had similar problems ?
