You are already past Cobb Stage 1.
Cobb Stage 1= Completely stock WRX, Accessport stage 1 flash.
Cobb Stage 2= WRX with turbo-back exhaust, Accessport stage 2 flash.
With the mods you have right now(how your car is exactly this second) you would benefit most from a dyno tune.
Also, you don't need a BOV. The factory BPV is good and will hold boost until about 22psi.
I saw the update that you already went stage 2 and beyond. Good luck w/ the car.
