What does Myna really do to a IP?

[CoyoteStarfish]

Al l I can gather from obvious sources is that Myna changes out the pump elements, along with some fancy external adjustments.

No details, however, on how the element transplant is done.

I'm starting to wonder if a competent machinist couldn't bore out the pumps for larger elements and achieve similar results minus the external adjustments.

Even larger pump elements are not readily available (which I gather that they are not), it wouldn't take a rocket scientist to mill new elements.

A little trial & error and you have pumps close to that of the Finns at half the price or less?

Provided; I do not know exactly how these injection pumps work, so I might just be pissing in the wind with this post.
