Did your stock 18:1 setup have a delay chip? Maybe compare where the first (pickup) tooth on the stock sector gear is in relation to the tappet stud and what it looks like on the new sector gear. From what you're saying it sounds like an issue with the sector gear/tappet stud not the tappet plate or nozzle.
I've tried 2 different sets of 13:1, both with and without delayer chips. Neither worked, stock 18:1 had delayer chip. Gonna try those gears tonight and see
yeah id check the bucking, I built an ICS m16, and it was having feeding problems, changing nozzle size didn't work. the problem was that the hopup bucking was protruding into the feeding chamber stopping the bbs from loading, all I had to do was trim a couple millimeters off and it fed.

He says he already did, and says that with the stock gears it would feed perfectly. If he's right, then something about the sector gear is tripping up the timing.

I have epm1 and epms. I also have mags with maple airsoft springs which are stupid strong that I've tried. The mags feeds perfectly 40
Rps when active brake is on.
Try removing your mag and firing it upside down by putting BBs in the feed tube by hand. That will eliminate the possibility of an over-tight mag spring, and actually any mag-related problems.
Watch the first 3:40. I think he does not PTS mags...
If you end up watching the whole video, keep in mind his views on the Maxxx HopUp Units have changed for the better. What I mean by this is he realized just how bad they really are.
The max hopup units last I checked had like almost a 8mm clearance in the feed tube and chamber. And they have a offset feed tube due to a off spec issue snagging the bbs as they feed. It's like they didn't double check their design and focused entirely on the modular hop arm design they have.
If they just fixed those two issues then it would be literally the best m4 hop up ever designed. But the shortcomings still stand.
Seems many cnc shops struggle to properly design things these days.
Most "fail" to see the "big" picture. They see just a segment and work around that and not the big picture. Plus, again...lack of standards too.
If they would "measure" a TM...they could make it better. Most likely they took a low cost unit and tried to improve that...or a clone of a clone, Prowin hop-up...
