wondering the same thing about the IRC. There are several top shelf blippers on the market and its hard to tell the difference re performance, functionality, reliability between RapidBike, BlipBox and IRC. The main difference with Rapidbike seems to be their EVO fuel management module which you have to have to get the blipper (its not a standalone, you have to have both) They say the deal with RapidBike is that it is "auto adaptive" constantly changing fueling depending on the variables they have selected for. Maybe thats a good thing, a great thing or just a thing. I don't know.
