If you are using a MS style PWM to provide the hold current then start =
at 1Amp per injector, which is 10-15% duty cycle for a 2Ohm injector. =
Adjust till it works. Once you are tuned in, it may be worth backing off =
a little until you reach a minimum reliable hold current.

20KHz?  Your not goin find and injector to operate at that speed.
