When My IMRC went out on me, The Cable was frayed at the end where it went into the IMRC box. I didn't feel like getting a new one so I removed the butterfly valve off the LIM. In other words no secondary's (sp?). I've seen dyno plots proving you get a 1 or two HP on top end. Also you can do the work yourself. It's not hard to do. You could also get the IMRC somewhere other then the dealership and put it on your self.
