Not if it's broken, no lol. You just did try it, that was the whole point of the exercise. 
Basically, if the ecu isn't getting maf readings that are close to what it expects, then it resorts to a set of "safe" default values, ie low values which will make sure the car doesn't smoke, but also make it feel down on power. Unplugging the maf forces the ecu to resort to these default values, so if there's no difference between maf plugged in and maf unplugged then the maf is dead and needs replacing to restore power and economy.
Do you have one of those stupid K&N style filters? They're known for killing mafs.
