The pulses are large because you have a high volume injector squirting into a very small internal volume, and it is squirting an incompressible substance. So any teensy weensy change in the volume of liquid in the loop is going to have an instant response. Which is what you want as far as quick response to AFR/boost etc. But not what you want when trying to maintain steady state. putting some sort of damper in there will also dampen the AFR/boost response too. The stepper motor was progressive, so for whatever other faults it had, it avoided this issue.
What you need is an injector system that works progressively rather than by pulse.
