Swamps does some kind of frequency modification to the IDM that Beans doesnt. I asked what the gains were in the difference of the two and the guy at swamps said that theirs is supposed to flow more than a stock IDM. I was under the impression that was what the resistor was for.(that and to make the pulse width shorter)
If I were going to pay to have it done. I would go to Beans. It is about $125 cheaper there and I have heard you can tell no difference in the two IDMs.
