Hello,

Does anyone have idea why I can't have more boost at high RPM? I have talked with people at Bootmod3 and they said it's limitation of PWG stock turbo. Is it true? Why is my WGDC at 60% if I miss so much boost at high end? Should be more to fully closed (100%) if I'm not mistaken? Beside that can anyone please check overall health of my log, is there anything more I can do before going on turbo upgrade.

LOG link (my boost is shown as bar, not psi since I'm in Europe). I miss approximately 0.5 bar or 6 psi on high end.

Correct. 10-11psi is all you will get from stock PWG. Also answered you at Bimmerpost...

It's easier to get your logs looked at here if you use the built in datalog feature and embed it in the post. If you are using MHD, they are integrated into this site so you just press the button and the logs appear here. Then you copy in the BB code into this thread.

With proper tuning you'll be able to hold a bit more to redline on this setup. I wouldnt say 15 psi but you may be able to get another 2 psi out of it by redline.
