Having tried this myself, I can state:
CON injection rate still not particularly adjustable, and still not super
efficient. And because of the double flow restriction (needle +
diffusor), I found it's difficult to make adjustments to the needle valve
once the diffuser is installed (the feedback takes on the order of an
hour). It's better than NOT having the needle valve, but still not as good
as using a true reactor system downline.
