Hello, I'm new to the whole Accessport and tuning scene and I don't know whether Im in the right forums for this. I recently tuned my 2020 Subaru STI car with the AP to stage 1+ SF intake. I have been tracking my feedback knock and fine knock learn. I just installed a boomba BPV and everything seemed ok until later in the day when i started receiving higher knocks when i would sort of step on it. Registering -4.20 or -3.60. DAM stays at 1 which is good. Any help as to what it might be or if it is normal, Although i heard that between -1.40 - -2.40 is normal. I just need some help please. Thank you
