so I have the Sir2 in and it was running perfect, and by the way now I really understand the meaning of Ahhvtec's username lol but anyways when I am driving it is not running completely smooth, it like stutters or jump's just a hair. it doesn't matter rather it's high rpm's or not it will do it if I am smoothly shifting or getting on it, and when I get on it a little it definitely sacrifices some power...any idea what this could possibly be? and also not every time but sometimes when i am just sitting there it wants to idle back an forth from like 900 rpm to 1300...any help or suggestions would be appreciated...
