I am looking at buying the titanium Akrapovic headers to go with the end can I already have. I have read from a recent thread on here on Power Commanders that I should use one of these in conjunction with the exhaust. My question is will the PCV work on all three of the riding modes (I do not use Slick) or will it just be set up on the one I choose, probably Sport. If it is set up in Sport how would the bike run when I occasionally switch to Rain mode?
