Sorry Bibie looks like I'm putting you wrong..... I was under the 
impression that once a system went to closed loop mode it stayed 
there to optimise fuel economy not usually power? 
Hence the reason for getting an aftermarket chip or complete 
system.....as well as the ignition mapping & boost control.
