so on the way home from getting an oil change, i heard a loud *poof* of air, then i noticed my boost gauge was just sitting at 0 no matter if i was idling or driving. now the car is driving fine, i do hear a little comp. surge though if i try to gas it a bit, but i tried to keep it under 3k rpms now when i got home i popped the hood and looked around but i didnt notice anything different. i do hear some sort of hissing towards the firewall but i dont see anything that looks wrong. anyone ever have this problem here? oh and its a blacktop s13 sr
