Ok so I'm somewhat new to the suby world. I've looked into AP's and am trying to find more info on Opensource, but am struggling with finding any good info. I could be blind but just looking for direction and any advice. I am running an 02 wrx w/ injen cai, 3 in. cat-back(waiting for EM to do TBE), and a turboxs BOV(possibly removing). Looking to be around the Cobb stage 2 area. Thanks!
