did you have problems with the factory regulator and that's why you changed it?
with factory settings and with jsb exact king 1.645g (25,39gr) i achieve 230m/s (754fps). and that's not enough for me, and that's why I'm planning to add a plenum, that huma plenum is 12cc, right?
I had no problem with the original regulator but I wanted a larger plenum so I put in the regulator with plenum of huma, it still needs to sit a bit.
I also enlarged my ports to 5mm.
These are my first test shots on the FX Chronograph.
