So I know there is a lot of information about the PCV but I can't find the info I am looking for. So here it is. I am going to buy the PCV w/ ign for my 2011 900 custom. My question is, is it beneficial to buy the Advanced O2 Optimizer dual channel product as well. I have vance and hines pipes that have spots for o2 sensors so I could easily hook it up. I am just wondering if anyone has this set up and if I should go that route. I would like to not have to take it in and get it dyno if possible.
