I just installed a Magnaflow 3' Catback, I also just bought a used an "Un-Married" V2 Accessport. I'm trying to go Stage 1 at the moment on a 2011 WRX Limited. Stock Intake. My question is:
Do I just install the Map given to me on Cobb's website (for California) for Stage 1? Or is there something else I should install?
