This is a cut and paste from my build thread:

Alright, I got my injectors back today from WitchHunter Performance. They look brand new! Lets hope the work like new...

I am confused about one thing on the detailed printout they sent. It shows the injectors resistance @ 14.
I tested the resistance before shipping them out as they asked, and they tested for me @ 2.8. I saw the print out and was like WTF?? So I just tested them again and they again came up at 2.8. So that inspires confidence in their work...
But the rest of the data looks fine to me, the injectors actually look as though they were decent before cleaning.

So what are your thoughts on the resistance readings?

its strange they dont give the units on the flow sheet. i would give them a call if your worried.
im assuming those are stock turbo injectors
2.8 is within spec so i wouldnt be worried

I'm not really worried to much, I'm sure they are clean. They ran fine before I pulled them, just wanted to have them cleaned and tested to be sure.
I just don't know how accurate that data is...

The owner of witchhunter is a buddy of mine out of bothell, wa. He does extremely good work, and has over twenty years experience with injectors including rebuilding and cleaning. Now, what i do know is they are flow tested on a bench machine, so this could be resistance to flow. So my guess would be that the resistance is in the machine working testing the flow and giving a resistance to it.

Also, what you want is your injectors to be within 2% of flow within each other. He had a set of mine for an escort gt i was building flowed within 1% of each other. I can tell you it made a large improvement on the idle, throttle response, and tun-ability.
