Series 5 fuel injection.
 
Just wondering if anyone has put Turbo (550) fuel injectors in for secondaries on an NA S5 and kept the 460 primaries?

Would the stock computer read and give out the same signal to the injectors?

Would one need to use the turbo fuel pump when doing this?

It would be done on a SP motor.

Thanks, Robert.

I have. You will definitely run richer. I was using an upgraded fuel pump, it was a T2 or maybe I had gone to an FD pump by then. Was any of that necessary? I'm not sure. I was troubleshooting a lean issue at the time (this was back in '05). The car made 172rwhp on a dynojet (ported s4 nonturbo).
