Tuning Dual transfer port

[fr.22impact]

What is the advantage to a dual port. My gun shoots great now.

Reg set at 95 power wheel at 2 jab. 18.2 ar 915 fps.

So what do you think?

The dual port is meant for people who are looking to shoot slugs or heavy pellets. It allows for maximum air flow so you don’t have to crank up the reg as high. If you are happy with your accuracy and don’t have a need to shoot slugs you are good. On my dreamline I got roughly 35 more FPS with the same tune only changing the port.

Or you can lower your reg pressure.

I gain +/- 30 fps after installing dual port so I lower my reg pressure to be where I was before and got more shoots per fill, but with 95 BAR you got set up right know I'm not sure how much lower you can go,

Thanks for the info.

Here are some photos of 70 yards knock outs and jsb

My Impact mk2 gained aprox 40 ft/s replacing both TP (huma v2) and pin probe without touching anything else. I noticed a substantial drop in shotcount though. Maybe I need to make new adjustments to make it more efficient.

If your happy, don't touch it! Sometimes small things can be like Pandora's box

If you were hunting or wanted more fpe and wanted to shoot 25g JSB at the 18g speed.
