i'm sorry but im really confused. when i got the DP fix for the jb3 know one ever said only to run it when your going in for NYS inspection. and in this thread at least one person has said not to leave the DP fix in when you dont need it. so i'm confused what the differences between the jb3 DP fix and the jb4 built in DP fix is. thanks
