Hi, I have a question for people that actually have an intake on their B38. I have a Vip intake on mine and I could hardly hear the bov or the turbo spool. Only incertain gears and only around 3k rpm. All the videos I have seen in youtube have a very loud and distinctive bov and turbo sound. But mine doesnt seem to make the same sound. Is it a B38 thing? Are the only cars that have videos on youtube with the intake are F56S? Any help would be much appreciated.
