No point changing the injectors yet as you won't have enough power to max them out on the standard turbo....
The injectors you fit should be the correct ones not the biggest , by that I mean that they should suit your desired power output...
If you are fitting a 400-450bhp turbo then 650cc Power Enterprise injectors would be perfect , have a chat with Bob as he is mapping it and you wont go far wrong...
