I drive a golf 5 gt and I wondered at which rpm I should shift to get the best 0-100. For reference this is its power curve (grey=manufacturer, red/green=actual) But I feel more like I loose a lot of torque at 4000 rpm

You’re trying to maximize the area under the curve here. So in this case, run it to the redline, shift, repeat. Shifting from the redline will drop you down lower on the curve, and the lower on the curve you are, the less power you make, which is less acceleration.
If you shift before the redline, you spend more time in the part of the curve that makes less power.
You should shift at the same power (kW) that the engine drops to after the shift.
For example, if the engine drops to 4500 RPM after the shift and the power at 4500 RPM is 110 kW, you should shift at the RPM that occurs after maximum power when it reduces to 110 kW (7100 rpm???).
While power gives you max Speed, torque gives you acceleration. And you would accelerate fastest always driving out each gear. But that is only the best way to get to max speed.
Since 0-100 is limited, you want the highest acceleration the entire duration. You actually don’t need alot of power to be able to go 100kmh. 50hp is more than enough to reach 100kmh, if you give it enough torque to accelerate.
Edit:
This dude explains torque and power really good: https://youtu.be/LUgjpDMcwpI
