Finally got around to installing the FX Power Plenum 720 on my .25 Impact with 600mm STX liner, with Reg set at 100 BAR, hammer maxed out and valve adjuster backed out I am right at 958 FPS W/ JSB 25.4. I turned valve adjuster in until I was right at 937 to 940. With a 12 shot string, Amazingly velocity hardly varies at all I am very happy with the results. As far as accuracy goes it stacks the JSB's at 70 yards. Gun is really efficient with air too. I didn't have the correct spring for valve adjuster so I used what I had until the correct ones arrive, but I don't know if it's worth messing with.

Definitely good to hear. I’m waiting on a piece from FX to do the install; I have one of the smaller ends so the power plenum wouldn’t fit. Been waiting for the part for a few weeks now so hopefully it will be sent out shortly.
Received the tracking number on Friday but it is still awaiting pickup.
