So im not gonna lie im new to working on a turbo car. Usually was a truck/beater car type guy. But anyways my car is a 2011 wrx. All stock when i bought it. Just has a nameless muffler delete turboxs 50/50 bov and a mishimoto intake. Car was running fine with 0 problems. One day i was doing a 3rd gear pull and at about 4000 4500 rpms is started to stutter and hesitate. My first thought was boost leak. Made myself a tester and bov was leaking. Replaced with stock one and installed a boost gauge. Still had a leak so next step was IC- TB hose. Replaced that. While that happened bolt snapped in the turbo. Got that out got everything together and still not running right. Idles and drives fine just not proper boost. Vac is -12 according to my gauge but i cannot find a leak anywhere. Can someone point me in the right direction.
