DE UTR-45 power problem after jam

[pyromancer6]

Had a pretty catatrophic BB clog/jam on Sunday's game day with the UTR after it was struggling to feed with the ZCI plastic M4 unit that I put in it alongside a longer 6.03 and a ML macaron, and ever since clearing the jam of around 10+ BBs through the hop-end of the barrel caused by an unlucky shitty BB the power's dropped by almost half, even with the hop completely off and even with changing back to the original hop unit to fix the feeding issue for now - any ideas? (around 1.04J to 0.633-0.673, varies pretty widly - feeding has resumed back to normal since changing back over to the standard intergral nub DE unit though)

Was thinking the jam and the very few amount of rounds through it not knowing it was jammed [as it was struggling to feed, originally just thought it was that before I realised it had clogged] has done something gearbox wise, maybe some sort of damage to the nozzle or other air seal compotents? It seems to cycle perfectly fine still and the falcon-fire hasn't started beeping or getting angry yet so I'm assuming the gears are good still.

Any pointers would be appreciated - I'm really not looking forward to opening the thing up though. Considering that this was my workhorse "it just works" ''backup'' gun I'm a little mad at myself for tinkering with it and seemingly fucking it up, but I guess you can't make an omlette without a few eggs rotting, or something along the lines.

And things were going so well..
 

EDIT:
 

Decided to throw in my desperate attempts to try and fix the feeding problem with the ZCI unit via trial and error here for good measure. If anybody's managed to change their UTR over successfully, please do tell what you've modified to get it to play nice, cheers. I'll take a second stab at it again if I can get this power problem figured out.

You are going to have to open it up; it could be the nozzle, it could be the tappet plate, it could be the piston, it could be an airseal.

Yeah you'll need to look inside. Jams can damage stuff way back.

I've possibly misunderstood what you are asking here - but i have always run a ZCI plastic hop unit, complete with ML Macaron (and i think likely, an omega nub but i can't quite remember)+the original barrel in my UTR 45. Out of the box i was getting weirdly inconsistent power and hop (entirely unusable), so had to switch out the hop  etc . And its been absolutely fine ever since....

I was getting average (but reliable) performance stock so decided to try the ZCI plastic rotary unit alongside a ML Macaron + gearworks omega nub, and while the performance was much better it just really struggled to feed for whatever reason. I was assuming that other people had modified their units to fit hence the request.

I did change the barrel over to a longer 6.03 (320mm) brass barrel out of a fucked second hand LT-52 I had lying around instead of using the standard 230mm 6.10 that comes as standard when I changed the hop and bucking, however - although since I put the old hop unit back in it's started feeding flawlessly again even with said barrel and rubber (the nub is internally fixed with the standard unit so I couldn't try the gearworks nub in there unfortunately)

 

So yeah, not really sure. Airsoft will be airsoft. If you ever end up taking yours apart for a clean or something similar I'd be interested to see what yours looks like to see if there's anything glaring that I could've missed
