Hello! I feel like I have a bit of a beginner question here. I recently bought a car with the 1.8T AWT engine, and it came with a tuned map designed for a K04-015 turbo. I’ve since upgraded to a K04-015 hybrid turbo, and now I’m experiencing some overboost. I’ve done some logging (attached), but I’m not quite sure what’s causing the issue. I suspect the map might be the problem, but my friend believes the map is fine and that the overboost is coming from something else. Any advice would be much appreciated, and I’d be grateful if someone could take a look at the logs.

Shouldn't the wastegate opening act the same exact way as on the K03-029/K04-015? The crack pressure on those stock wastegate actuators is 0.6bar iirc, and he has an 0.8bar spring in the actuator of his hybrid + a brand new N75.
What actually causes this? Not denying your findings, just genuinely curious
