Tuning Umarex hammer tunes or mods

Anyone still interested in the platform? I've had mine for about a year, and can share how to do some tuning that works for me. It's a bit of a PITA, but quite useful.
Yes what was you able to do to the hammer to tune it. And is it a regular ninja regulator. My hammer has developed a very slow leak and trying to find it. I also noticed on a few YouTube videos of the hammer that the air tank had been changed to an aluminum tank. So just wondering if one could get another regulator and tank to have for a spare in the field

I found Reg on eBay before I got hammer, and I got another one on eBay with a ninja 68 tank for $120. I bought a seal kit also from eBay to have a spare. All 3 regulators are identical. The brand new one came with 3 shims. The hammer came with 2. And the one with bottle, came with 3 shims. The kit came with 3 shims. I haven’t looked for a bottle for the gun, since I can teather it to 68 CU tank , and have about 8 shots on tap. 1 shim it shoots slower but you get 2 extra. 2 shim stock, and 3 shims according to Ninja Manual bumps it up to 3200 psi. Haven’t tried more than 3, and don’t intend to, because it shoots amazing. In its current configuration, I’ve shot over 1k rounds, and still holds air w/o leaks. That’s a 380 gr BT
