Having a huge problem with my bolt on 2013 Wrx. Mods are stage 2 plus EWG and FMIC. Protuned and all that to 340whp and 360wtq. Im having a problem after doing a quick 3rd gear pull last night. Sounds to be a knock but I data logged a few minutes while it was making the sound and didn't see anything out of the ordinary. Its so bad to where I don't want to even drive the car. Sounds like valves are slapping around in the engine. Check the oil with good oil level and still good oil. Im wondering if it could be my transmission or clutch because when I engage the clutch it seems to stop the noise. Its so loud it can be heard over the radio and just is scaring the crap out of me. Im wondering if anyone has had similar issues or anything closely related that might help. Ill link my datalog so you guys can take a look.
Any advice or opinions would be greatly appreciated. Im planning on taking it back up to my tuner and I already emailed him about the issue but hoping someone on here has had a similar issue that can shed some light into what it may be. Thanks and happy new year!
