it's really too bad that no one on this site has read this and can give you the MAF spec value in mass/time at a specific RPM at a particular shift point. I do not believe that this spec is available in the FSM. I got it from a MB tech (friend) at a dealer that had access to this readily available technical info. With that info you could test your MAF. The trim values don't tell you the MAF real time measurements.

Is your car accelerating OK. Does it have full power. Why does changing the MAF change your trim values. Are you reseting the trim values each time you retest?
