Hello all,
I recently upgrade my FX IMPACT X with power plenum kit and with 700mm .30 barrel. I find out when I increase reg pressure from 125 bar to 135 bar, I actually loose velocity from 933 fps to around 920. I am shooting 44.75 grain jsb exact pellet. I have maxed out tension spring. further increase reg pressure seems does not help. what is it going on here?
any help is highly appreciated! Thank you.
Regards,
S.W.
