Pete & Bubba,
My thoughts about a FRK-module is that is not fine-tuned like a Rapid-bike module (or other adjustable modules), so the A/F mixture is a guess (every other motor is slightly different), you both know that BMW engines are running lean and putting an other exhaust system, catsectomy or catless heathers on the bike ... the bike run's leaner than before ( leaner is hotter with possible damage to the valves or/and pistons)
(Bubba ... you know) I'm running with a Full Akra system (this system is developed by ... Don de Vink !!!) and a Rapid Bike module, fine tuned on a dyno (Tovami, Ruud Fredriks) so I'm sure the A/F mixture is more then okee 
Got a lot of bottom power and no big hole in the torx curve 
Running with or without the butterfly valve makes no difference, the valve is developed to be a noise reduction device for going true the EURO norm tests !!!
