Just trying to get an idea of what size and brand fuel injectors everyone is running with a boosted 6.0L. The goal is 600+ at the wheels and I was hoping siemens 60#ers would get me there without MAXXING the duty cycle. Also, I plan to run a Bosch 044 on a return system with an aeromtive regulator. What do you all think? Should I go with 72#ers just to be safe or would 60's be OK?
