Haven't tried one in my NC but I did install one on an bmw r1200c Montauk. Turned out to be a wonderful upgrade to improving smoother running from idle to cruising speed. Also improved gas mileage ; a great mod for our fuelly folks as well. If I remember correctly how it works is it basically overrides the current settings in the fuel injection system and "takes over command." A neat little component that did make a difference on the beemer. Thought about installing one but putting my $ towards other farkling for now. Would have absolutely have no reservations on anyone trying this and was super easy to install.
