Set nmax to 7200, lift it well out the way. Also set KFZW/min to -30 at 7000.

Meaning KFZW lowest load , first column 7000 to -30 ? Or ZWMIN maps ? Sorry have not yet stumbled on them . |

adam-, it seems You know your stuff about pops and bangs. Could You please tell me why changing KFZWMN + other maps does not have effect ? I need to change KFZWMS to get the effect.
As i understand KFZWMS is for engine protection. I also had to change it for hardcut limiter to -30 for kfzwmn take effect.

Original garret which came with turbo . Rated 1bar actual pressure tested 0.90-0.95
Actuator seems ok, tested multiple times.
I am still suspecting n75 as the oem started acting wierd, had aftermarket BS N75 on shelve but acted same.

Actuator is moving freely when pressurised. Holds pressure

Sorry for quote. It was misclick Also to mention if i regulate boost with pids to 1.2-1.3 bar, then it is controllable. But i was not happy with that setup |

If you 100% sure that wg fully opened
And the boost pressure higher than wg spring
Then it's just a small wg hole. The Chinese crap usually comes with it

Had same tought, but its original Garret. Will detach wg from flap and test if there is full movement. If it is actuator, are there suggestions , which producer to use ? Mamba, turbosmart etc? |

Tested today. It seems as if actuator has too small movement and it opens wg flap ~75-80%.
Actuator code : A480009-6
Exhaust side : 449010-1
