Has anyone got a sure-fire way or tutorial on setting up a GFB Respons correctly on a stock tune? I've seen the GFB video on the gen 2 WRX but I am wanting something a bit more specific to our cars. My car also has the Genome rear mufflers which even with the stock BPV makes a bit of exhaust popping vs the stock mufflers so I don't really know how much is too much.
