I routinely run Valero or whatever the cheapest+closest CA91 is and I never see any excessive knock retard on "lower quality" fuels. IOW, I hunt and peck for cheap gas just like anyone else filling the tank on their DD. Your tune shouldn't be so ragged-edge that it requires a specific brand of gas anyway.

Does anybody have any ideas about the max and min duty cycles being funky?

No idea but first some troubleshooting. Have you verified that your solenoid is hooked up properly in regards to vacuum and electrical? One thing that I am thinking - what ECU do you have? Have you verified that the ECU you have provides power when 100% or ground when 100%?
The way MY car is set up, I have 12v coming from... somewhere, I don't recall, and going to the EBC solenoid. Verify that you are getting 12v to the solenoid.
Next, verify that you DON'T see continuity with ground when you test the other feed to the EBC solenoid at 0% duty cycle. Then test at 100% duty cycle and see if you are getting continuity with ground.
Then, verify that at 0% duty cycle that you can freely blow through the ebc solenoid using the ports you are using for your boost controller. (I don't have a EFR so I can't tell you how it all goes together). Finally, put your ebc solenoid at 100% (you should hear it buzzing if it's like the MAC solenoid) and check to verify that you CANNOT blow through the solenoid.
Also, I see that the frequency used for the EFR solenoid should be at or less than 32hz. Make sure that a compatible frequency is set in boost control settings.
If all of the above is correct, you SHOULD be able to at least tune open loop.

I seem to remember that I couldn't get the EBC that came with the EFR to work with my MS3. This in and of itself means nothing as I have no idea what I'm doing, but I seem to remember @18psi couldn't get it to work either, so I've tagged him so maybe he can give some input.
The 4 port MAC valve works great though.

I have tuned several EFRs with the standard EBC valve on MS3, so there's no inherent issue with the combo. I'll post my EBC settings in a sec. They aren't perfect, but they are close.
e: Ha, pretty basic. I'm sure this can be improved on. I don't think I've actually determined min/max and the delta should definitely be lower. I've spent most of my time on the slider bar settings and advanced PID, but I also haven't focused on completely dialing it in yet.
