I love the zelos, its crazy accurate but its just too powerful for where i currently live and its pretty loud even with a somewhat decent moderator. Is there a tune where i could get it down to about 20fpe? i don't know if i need a different hammer spring and also what regulator pressure would be best.
Tuning Tuning down a Zelos

The regulator as set around 2100, I we'll check the manual to see what the lowest working pressure on the reg is and set it maybe 100psi above that. From there back out the hammer about 2 to 3 turns and see where that lands you. Then turn you hammer in or out in 1/4 turns till you get the speed and accuracy that you want. For starters anyway.

Reach out to C88 machine. He has a weaker hammer spring that comes with the liner kit but he might sell it to you individually. When I tried it out it was getting 24fpe but I had the reg at 160 and never ran it at a lower reg setting.

Why not buy a quality moderator from donnyfl. Seems like you are more concerned with the noise level. With a proper moderator you can quiet anything down.

i don't find a normal donnyfl mod to be very effective, its an outdated design. I do hear good things about yokozuna though and from a internal design it looks good but his other moderators are really not great. I had a tatsu and tanto for my FX dreamline and it didn't perform nearly as well as i thought it should. I think the issue is also just how much land and neighbors you have to deal with so what is sufficient quiet for you wont always be good for everyone else.

Those moderators are on the small size in diameter and length. I have two ronins and one emperor. They drop the noise significantly, especially the emperor being 10" long. You can also wrap the core with felt and zip ties to absorb more sound as well.
