I was looking through the possible maps for the pcv and didnt find any for the m4 street slayer. I also don't have an air filter but I was gonna get one if I heard good things about adding one over stock. Total mods are -1/+2, ivans wire mod, m4 street slayer, pcv. Does anybody have a similar setup/ advice on the pcv settings? And what improvements did you guys see with a new air filter? Thanks for your help guys!
