Hey everyone! So a couple days ago I brought my 09' WRX to a local shop of mine, the dude was a master mechanic at subaru so he knows all about our EJ's and such. So I brought it in to him for a boost leak test, and he said he didnt find anything at all for a boost leak, and that my car drove mint. So, I bought a new Cobb SF intake yesterday and took out the old CAI that came with my car and it was absolutely disgusting haha. So i did that, put on the new Stage 2 plus tune since i have a turboback too, anyway the car runs alot better now, but still not hitting anywhere near target boost should be, (17). I've had this problem since i've had the car and i have no clue what it is but it almost sounds like a metallic fluttering noise, like when i start getting into boost it starts coming on and its pretty deep and loud. My car is still pretty quick though, Im only hitting 7-10 psi max at wot and only hit like 3 or 2 in first gear, so do you guys know any recommendations? I've posted about this numerous times but I don't think anyone really cares about this topic haha. So please help me out if you guys know anything. Thank you!
