I refer you to the previous thread and links to Steve Dinan's white paper regarding Dynamometer Testing and the Modern BMW Engine
This seems to be the logical next step.
One quick Question Sir Ks frog man! Did it Help and Where are the pics?????
or could it have been cleaned?? and you missed a sensor like the infamous mass air flow sensor blah
