Tuning FX impact m3 .25 cal 600 mm barrel 34gr pellet tune and fps

FPS and tune for a 34gr pellet

 

[18.13]

Somewhere between 830 and 900 fps. As for the tune no 2 guns are alike no 2 barrels are the same and no 2 gauges read the same you'll have to figure that out your self

Nice 

Try 150 and 100 to 110 should put you in the neighborhood may have to mess with power wheel and micro power wheel around max and micro I'd try 3 or so don't forget about the valve adjuster to you can try 4 th line but may need to open it up more

I have the same gun on order. Excited to figure this out. As I tinker with tuning has anyone found much difference going back to the starting point and trying again. Or when I go back to the start are things a little different? I would like to know no matter how much I screwed up I can always go back to the start and try again.
