Is this because the car's getting hot? You will loose power due to this. Might want to get an upgraded IC
Hmm...few replies. I agree with KittyMini. I'd bet the MINI is getting to the top of its recommended tempature range and is reducing boots to keep it from overheating. It would be best if you could data log to see what the ECU is deciding.
Missed this thread somehow. I never experienced any significant power loss during lapping, but never ran it hard at temperatures that high either. It's probably just too darn hot like Kitty says. Let us know if you sort it out.
