Usually these chips are just a box with a resistor inside it. It may (or may not) provide a very small change in power, but it definitely wont do what it advertises. In addition any change it makes will be overcome shortly by the ECU relearning. The only way to increase power to the M would be to get it tuned and/or to add mods to the car. The best tuner for the M cars is UpRev, and I do not know if they support every area of the M37 and M56 yet as those are newer engines.
