My regulator pressure is measured with the Sekhmet digital gauge in place, the other side of the EAR

Your barrel is longer, so you'll achieve better speed at a lower reg, plus the new EAR reg does have to be cranked a little higher than the old inline reg I think, due to its design, but has a boarder spread.

Yes but mine has same barrel length, but maybe slightly lower friction, compare:
350mm
.22 calibre. Same.
Ammo: JSB Jumbos 18.13gr. Same.
Reg:
Puck: full sized. same.
Jets: 2 x 1.2mm. Same.
Speed: 900fps. 919fps.
Shots per 300 Bar fill (standard cylinder): 30. To quote Harry: in all the excitement I ...
That should not make any difference, the new reg may have a bit lower flow and longer reset - Bar is Bar - what you see on the manometer is what you get
My take so far, the new valve housing without the dog bone and collar is not the same as the old valve housing

With the EAR, apart from being able to easily attach a gauge & quickly adjust the reg....I just seems the previous regulator /plenum setup (as you have) seems much better

I do own an extra back stock with the EAR and the new forward plug
In the weekend, if I have the time, will take it apart, remove the dog bone and collar, set the reg at 120 and compare the velocity to the original back stock

Dismantled the valve housing after first test to remove the dog bone and collar
Found the o-ring on the EAR valve housing bone dry, no trace of any lube whatsoever
BTW exact same problem with my last two Leshiy's, came with zero pressure, was leaking, o-rings were fine, added lube, problem solved
Manometer used in test:
The result, jet size was 2 x 1.2
Did not have the time to adjust the old valve housing regulator so only tested at 120 Bar
All targets, first edition valve housing far right:

Don’t quote me, but I believe the original reg had a larger plenum than the ear. Ed says this should not matter, but to me, plenum is plenum. You can definitely bypass this by raising reg pressure, and economy shouldn’t suffer. Looks to me like this is the case with all your testing.
Jmartinez is getting 84 shots on a 300cc bottle with original reg set lower and 450mm barrel. Compared to drseagram who is getting 30 shots on factory tube, which is about half the size of a 300 bottle, at higher reg pressure, and similar speed. This would show similar economy less about 20 shots (shorter barrel would confirm this). I say both of you have some pretty good tunes respectively.

To premise, I have the “ear” at 130 350mm barrel 350cc bottle, 2x1.2mm jets, largest puck shooting hades at 900fps for 85 shots before falling off reg. 250b fill.

Was going to chime in that I originally purchased the Yankee Hill 6" picatinny extension (Model YHM-9473) for around $52 to extend out my rail to better mount my Atlas bipod.. it worked well and I was happy with it but recently I saw that Saber Tactical had released a Universal Picatinny to Picatinny rail ( ST0032) that looked more robust.
It is a little more expensive at ~$79 but it is a lot more sturdy and also has an ARCA on it so that you could mount the Leshiy to a camera tripod as well. It is also a little longer overall. While the Yankee Hill worked great I am happy I upgrade to the Saber and if I was doing it again that is what I would order as it works perfect.

Just Keep in mind, the original rail is part of the poly body of the rifle, and actually flexes with a bipod attached. I’m sure this is increased by lengthening that rail out front with an extender. I use a handguard of some sort to mount my bipods. It tends to be a sturdier platform, and works double duties by giving more spots to mount accessories, AND protecting the barrel.

What's the highest pressure/bar people have tested for the REPR?
I currently run ~183 bar with a 50 grain slug at 850fps but curious if it can go much faster.

Agree but in my case I have a 250mm barrel and the Hornet kit so perhaps a different approach than someone that is looking at some of the longer barrel kits with the handguards like you mention. In my case I like the idea that it can be tucked into a briefcase sized Pelican case and carried to the range, or folded and put in a backpack. This was my first serious air rifle and I was so happy with it that I decided to add a 2nd serious air rifle and just received my FX Impact mk3 to play with as a more dedicated bench gun...

Hey bud I I’m running a 350mm .25 and I’ve been trying to tune my gun for a bit now and I’ve changed power jets and messed with reg pressure a lot I also have a 300cc tank and on a full 250 bar fill, I was getting 22 regulated shots and about 25 more unregulated shots easy with factory 180bar! And a pair of .4/.4 jets which wasn’t the best for me accuracy and speed wise, I was recommended to put a pair of .2/.2 size jets and turn down to 160. I was also told you should be running two jets cause it was made to flow through two. But Yes the .2 size would mean less air efficient but it would give me better speed with lower psi in the repr what I wanted. This maybe saving more regulated shots? So far liking the .2 size still have yet to do shot count but sitting at 160 bar shooting 34grainers at 55fpe and pellets 26grain at 50fpe. Surprisingly before I couldn’t shoot both slugs and pellets at same tune they would be opposite and way off but today I poop both at 160bar w/ .2/.2 and they were both right on sure only at 20 yards but more testing to be done soon. liking it so far

Just giving what occurred over the past few day’s with changing from .30 to .25. In the .30 I had .4mm for combined jets and had the reg, repr, set to 165bar and had 50.15 JSB’s averaging 895fps with 450mm barrel.
Using the Huma FX barrel adapter I switched over to a 600mm barrel and didn’t change anything and had 25.39 JSB pellets going over 1100fps! I remembered I needed to change the jets and the regulator pressure to bring that fps down to what I wanted, 890 to 910 fps. I ran out of the 25gr pellets and had to switch my tune thoughts for the 33.95gr pellets instead.
Changed jets to two .3’s and brought regulator down to 85bar and gradually increased reg pressure up to 105 bar to achieve the range with those 33.95’s at roughly 895 to 900fps. Next will be headed to the range to see how the FX barrel does on the L2.
Hope this is helpful…

In trying to get my head around the jets, is it the case running larger jets is more air efficient, yet requires a higher reg pressure?
So I currently run 2 x1.2mm jets & 155 bar, in my EAR 350mm .22, but for instance if instead I switched to, 2 x 1mm jets, could I then run a lower reg pressure, but would waste air per shot? And I guess probably cause accuracy issues with added turbulence behind the pellet?
Guess im just curious for someone to break down the differences & actual practical explanation of how jet sizes are used. Not just saying "dwell time", but explaining what happens & how experimenting with jets actually effects results with pellet speed, reg pressure & air efficiency.
Interested to read peoples input

Regarding your first question, the answer is yes *provided* no other variables are being changed, like barrel length, calibre, projectile weight, reg pressure, etc. The jets just control the dwell time. So when you change your barrel length, reg pressure, projectile weight, etc, the jetting while it make have previously been ideal, it may no longer be.
If your dwell time is too long, you risk wasting air and potentially making your projectile wobble or tumble a bit more than it needs. If your dwell time is too short, you might be missing out on some power.
In .22 I doubt there's much benefit in going to smaller jets unless you use a longer barrel or really heavy slugs. But I haven't done enough experimentation to be sure.

The moderator on my latest Leshiy 2 was off to the left, had to ad shims to stop the clipping, not perfect, took the time to fix it once and for all

It looks like you mounted it on a lathe to flatting the mounting face?
Was your moderator always off, or was it induced by something?
