another injector question on stock setup
I need new injectors for s5 t2. I was thinking about just getting the stock injectors for the sake of ease. But, can I put larger injectors on my engine with a stock ecu and wiring harness np? Also, I was looking at the fuel calculator i saw in another thread, 2x 550cc and 2x 720cc produces 212hp on a stock engine. Is this accurate? Also would I need some type of safc with this setup? Since I have a full RB exhaust I'm getting the fuel cut defender from RB, how will this effect me?

Lets clear something up quickly first....
Injectors DO NOT PRODUCE horsepower....
you buy injectors to SUPPORT the hosepower you HAVE.....
If you have the STOCK turbo on a STOCK engine and run 10-12 PSI of boost.. You should be FINE with your stock injectors.. BUT... nobody really quits modding and you will most likely need to step to 720s in the near future anyway...
YES.. you really should put an SAFC on there cause you are going to need to add fuel because the FCD tricks the ECU into thinking its getting less boost pressure than it really is, therefore, you should have something to compensate!!!

Your setup is a prime candidate for "boost creep"
