changing your impeller will give u more low end right? how do u go about sizing for a impeller. ive seen guys talking about a few sizes but it seems like they r matching to what there running. if this is right will u give me sujestion.

Pull your stocker out and have Dave at Impros bend it up.

Just call and tell them what you are after. You can buy a new one or have yours pitched. Make sure you tell them the altitude here in Utah so they can hook you up with the right pitch.
