I am surprised the car idles right. As others have stated you can not just put bigger injectors and larger turbo on the car and expect it to run right without a tune. There is a map for an FP 16g in the Accessport for an 03 WRX that uses 565cc injectors. Take a look at the map notes and see what it requires.
