You didn't really say how much boost you're running or what your current duty cycles are. The Bosch should support about 80% duty cycle on those injectors at about 25-26 psi. Typically that's about 450-500hp of fuel on E85. That's the pump I'm planning on running and I'm using a surge tank to feed the Bosch with 10an line. 8an to the rails. 8an to the regulator. Dual 5an return to the surge tank. I'll max out my 835cc injectors before I'll max the pump. If I was running dual pumps, I'd set up a safety circuit that checks boost level and fuel pressure using a pair of Hobbs switches. Not enough fuel would cut boost. Then again, I'll probably run that with the single pump...
