Update:

I went ahead and hooked up some resistors to the injectors and set MS to high-z settings. Car runs fine, tach works again and the warmup is working. Since then I have upgraded to the HighRes code which is running awesome by the way. Anyways I have the car tuned to 16psi and the duty cycles on my 650s are at 65%. So hears the question.. When I was running them as low-z injectors with MS at 15psi the DC was at around 45%. So Im assuming that not using low-z injectors the way they were designed and just throwing power at them with the resisters its causing them to not flow at their potential? If I were to switch to the Peak/Hold board would it lower the duty cylce of these injectors and push more fuel? Upgrading to the P/H board would be cheaper than new injectors.
