Stock injectors are high impedance.
I order for this thing to run right, you need a base fuel pressure of ~15psi and a working front O2 sensor connected to the factory ECU. The ECU can't trim fuel if it can't read the A/F mix, and with no front O2, it dumps fuel as a failsafe. No amount of SFMU adjustment is going to get you to a reasonable idle on the stock ECU without a front O2 sensor.
