Hi i have a strange behavior of throttle. At wot is runs like this. I was told that this is normal.

red boost, green throttle

 

The Accelerator Pedal and the Throttle are different things, the Throttle is rarely wide open for more than a second or two even when you floor the Accelerator.

Your Screenshot is also meaningless without the Units being shown.

Maybe this is better

That does make a bit more sense

After a few seconds the Turbo was producing its maximum Boost and stayed there. The PCM didn't command the Throttle to open fully presumably because it didn't need to.

So you think this is not a problem but normal. It dies this because it reached the wanted power? Here some more info with 3rd and 5th gear

check for faults if none, check software part numbers to ensure the car is std and not some 3 year olds chip tune bodge up - then run on a dyno and see what power and torque curves look like - if close to std shut the bonnet...

remember these days the computer plays silly buggers all day long - loss of traction will drop power-output via multiple engine management features - like ignition timing, boost control and throttle position (within the flyby wire system - not the pedal)

plus overboost for tiny periods so long as various parameters like knock control and temperatures are in the happy range
