recently i lost 10 psi bringing me from 19-20 to 10-11. im runnin a k04 with 380 injectors, forge dv, and a giac fx flash. anyone had this issue or know where to start. is this symptoms of a typical boost leak in the lines? havent dealt with a boost leak yet

 

quick update, now i cant even boost past 5psi, still have a p0432 cat code, so now im under the assumption it is a clogged cat after hours of research and someone saying they have had similar problems with a clogged cat, i can hear it when i shut off the car, sounds like a effed up muffler but it is comin from the engine bay obviously. ordered a test pipe so i will be putting it in this week/weekend. anyone had a cat cause similar problems like this???
