Yes you could change the airflow meter to a bigger one. I don't think the 1ggte would be the go. Try and find one from a BMW or Volvo some early european cars have larger ones with the same pin out. Pin out isn't every thing. Air flow meters are made up of resistors configured to make voltage dividers. The resitor configuration esentialy determine the fuel calibration. You could put the circuit board from a 3tgteu airflow meter into one of these large ones.
Becarefull of the output ie same range etc. People have had good success with the standard air flow meter ie 300hp with different injectors so I wouldn't worry my self in changing it.
