I'm going to take a guess at what your mean:
Does GM use saturated or peak /hold drivers for their LSx and Vortech lines?
Saturated in all as far as I know. However, I have never peaked under the hood of a 8.1.

Peak & hold & current limited/saturated. The latter is what is used on LSX & most motors that I know of. The peak & hold is usually used on low resistance injector circuits.
There are a couple more variations I think, but I dont think GM uses them.

P/H injectors have bigger coils then saturated injectors. P/H are more linear, have a wider flow range, and are less effected by voltage drop. Saturated are less expensive.
Saturated injectors will work on a P/H driver. But not the opposite.
Why are you interested in P/H?
