That is completely normal and that's actually a very slow taper compared to previous versions. |

My IATs was ridiculously low... I think there should be no tampering down.
Look on my second long above. Boost is 14psi (13,5 reall) at 6300revs. I think the car should have kept the maximum boost at these revs

Boost is always supposed to taper atleast slightly towards redline. Always. I dont remember the last time I saw a log that had boost at the exact same psi through the whole rev range and I believe holding max boost at redline is a bad idea?

This should be happening from 6500revs onwards, but i see that it happens earlier on my logs
