testing injectors: peak & hold or saturated?

I purchased some precision 450's and the person wasnt sure if they are peak and hold or saturated... is there any way to test them?

Measure the injector coil resistance with a multimeter.

2-3 ohm coil - Peak-and-hold injector
12-14 ohm coil - Saturated injector

Low ohm is peak and hold High ohm is saturated. You dont need peak and hold unless your going over a 660 injector then its best to convert over.

You can make either work, just make sure that your electronics can drive them. If they are P&H you *MAY* need to get a resistor box or a P&H injector driver module.
