I am changing out my stock injectors for R.C. low impedance 550 cc. injectors. The hp goal is 500 rwhp with about a 60% duty cycle on the injectors. My ECU (Autronics SM4) can operate high and low impedance injectors.
Anyone have experience or comments about these injectors? The R. C. part number is PL9-550.
