Is this normal? I installed both at the same time. It is a AGP WGA and Mopar BOV. I am getting about 12-13 psi of boost with wastegate only. Boost controller is turned completely down. The car stumbles and surges around 1800-2500 rpms. It feels like it is going to die then picks up the pace. I have tried dialing more boost in with the boost controller and the problem still exists. I turned the boost controller completely down until I can get this problem figured out. It is a 2004 stage 0.
