I can tell you it will vary. The mod'd Perrins will flow test from 780-820 cc/min or around 5% (all tested at RC engineering). That's around 0.5 AFR units when fueling full boost at the same PWM value. My two sets (sets of 4 injectors) tested very evenly between sets: 0.1% difference, but their average flow rates were set 1=790, and set 2=810. Hence, I don't recommend mixing sets together.

You have to state which "stock modified" injectors you speak of to get more help. STI side feeds or WRX top feeds?
