You will run rich, since the same air flow will now give a larger flow signal to the ECU.
The only way to really loose the AFM restriction is to remove it & go with a freestanding ECU.
EG: a Microtech.

Put a meter on pin 2E of a series four car. Turn the key to ON. Push the flap all the way in. Note the output on 2E. Now go for a drive. Pedal to the floor in the gear of your choice. Note the output from pin 2E. Now you should know if the flap opens all the way and at what rpm etc.

2E, on a series four, is on the ECU. It's the middle plug on the ECU. You look at the connector while its connected from the wire side. You count from the right to the left in a up, down, up , down fahion. Like 2A(ref voltage) is on the top row, far right on that middle plug. The wire just below is 2B(pressure sensor), the second wire on the top row counting from the right is 2C(ground), the one just below is 2D(02 sensor), and the third wire on the top counting from the right to the left is 2E (air flow meter).
