I would like to hear some opinions on what injector combinations would be good with the following mods:

3" intake
3" full exhaust, no cat
walboro 255
no emissions
v-mount IC
FCD
N370 ECU
SAFC neo
AEM wideband
Stock s5 turbo
Stock s5 Tii engine
Ported wastegate
HKS SSQV
boost controller

Is 550cc primary and 750cc secondary good with about 11psi of peak boost? Thank you.

you need some sort of fuel controller like a SAFC or a standalone to run bigger injectors.a stock ecu w/ larger injectors will only flood the car w/ gas.

i would suggest an rtek 2.0 ecu. or 2.1 if you want to wait a lil while. that will be the best for your setup.

720cc should be fine for up to 12psi. The stock turbo won't make much power past that anyways. Get a wideband and be careful when tuning. Depending on your future turbo UPGRADE you might need to go with larger primaries too (maybe even larger secondaries).

I have 550cc Primaries and 720cc Secondaries, along with the 255lph fuel pump for my BNR Stage 2. Bryan (BNR) said I can run 10PSi on my fuel setup so I don't see why it won't work on the stock turbo.
