What is the limit of power on factory injectors with factory S5 turbo......

Also just wondering if anyone could give me a rough idea of power with my setup.

13b extended port
550cc primary and secondary
Factory rail and FPR
Bosch 023 fuel pump
3 1/2 full exhaust
factory s5 turbo
HKS FMIC
Bosch coils and msd leads

Just having microtech ecu installed atm and having tune, but just wondering what i can be in for...

 

with that setup... get bigger injectors.
otherwise its a waste of money for the porting imo

now you may be stuck at around 250-260hp with a ported motor?
put in some 720cc sec injectors and you will pass 300
i had 310hp with stock ports/stock turbo with 550/720 injectors @ 14psi

injectors are not that expensive, but now you need it to be tuned twice
