Help w/B&M Converter 2400 Holeshot

Is anyone using one of these converters from B&M? If so, can you give me some driving/performance impressions of how it is working for you? It is supposed to flash @ 2400 but am curious to see what you are experiencing with it. Also, if you give me a quick rundown on your engine/trans specs, I would appreciate it. Also, any general comments on B&M converters would be helpful as well. TIA.
