Hi Ken, After some months I was doing the first log with the V5. In general the car drives quite harmonic. I just felt the power ouput in lower gears is somehow slightly lower. I did some logs and have some observations. For me it seems the regulatin circuit is not fitting perfectly. Anyway you may have another conclusion as I have just some basic understanding here due to my mechatronics study and being not experienced enough. In lower gears: The map tries to reach boost target and before it's reaching it drops WGDC down by not raching the target at all. Afterwards WGDC is slowly raising but in lower gears it's not possible to reach the target due to time and a slow raise. In higher gear it's the same behaviour but it reaches the target as there is enough time. Furthermre the regulation seems to be quite aggressive when it comes to a potencial overboost. It simply doesn't happen due to throttle closure. I saw in the OTS maps it's doing the same but lesser aggressive to slowly regulate to the target (+WGDC adjustment). It would be nice to get some assistance. Thanks a lot and have anice day. Best regards René
