Let's move the lever along the thread? and then compare with your measurements, the pressure will remain ,, the closing time or decrease if you move towards shortening the rod, or increase if towards lengthening.. maybe we can start thinking? that in addition to vacuum there are also dimensions of the mechanism.

What is the normal setup for a c43 amg ?

Would be good to show how to adjust as the video title suggests

Is this the same exact vac settings for a c43 m276? I put a new one on and measured the thread length in between the nut to the bracket that holds the actuator's studs to get it close enough, car has 80% power returned but I still have underboost code p029900, boost gauge actually goes over half way now on the dynamic select boost gauge, so I know i'm on to something...i'm a carpenter, everyone tells me to sell the car but it would make me depressed. Figured I'd ask before i slap in an entirely new turbo. I am young and don't make enough to get someone to fix it for me. Should the arm wiggle at all because i have it tight....sounds like the arm needs to be moving with barely and vacuum on it. Thank you, when i get my bread up I'll come visit yall....

Is it enough for 2.6 bar pressure?
