Sorry, that was from (shady) memory. Just been checking logs and 70% DC actually gives peak boost levels of ~1.85 bar.
The MVS may be way too small to allow for proper boost control at higher boost levels on this engine but I cannot see any boost creep on any of the logged data recorded so far.

Yes but it depends on engine configuration. On my original 2.5 8V engine the F38 worked great, as on the 3L 8V but I never ran more than 1.2 bar (18 psi) of boost on either. The 16V engine throws these observations out of the window, and I have not heard of many folks consistently/deliberately running more than 1.6 bar (23 psi) of boost on a 16V engine.
