I rebuilt my blower, and snout over the past couple weeks, and put in some new stock injectors which solved my 6th cylinder misfire problem. I also switched out some of the vaccum lines with some I had purchased from ZZPerformance. Now the car sputters like a cammed out muscle car between 750 and 1000 RPM bu..bu..bu...bu, and it wont read boost on the center led display, but the car drives and pulls just like it use to so I'm confused. I can hear a hiss near the boost bypass valve so I swapped it out and its still doing the same thing and I checked all of the vaccum lines. Please help
