I'll toss a scope on one of my injectors to confirm. If the ECU pulls the injector to ground for the entire duration of the injector period, it is being driven in saturaion mode not peak/hold.

I'm pretty sure the ECU uses a saturation driver with the current limiting resistor rather than actually having peak and hold drivers. Jeff L. seems to confirm this

Evey time I looked at this thread I cringed at the references to low impedance injectors as peak and hold but it's a very common mistake and didn't seem worth mentioning.
