I have been running my .25 impact on 160-170 bar and 970 FPS , b on the dial and 3 lines on front adjuster achieving 35 shots .
So I thought I would install a plenum kit from the UK, which comprises of , transfer port with two holes , valve housing which has been modified, pellet prob which has been modified , c3 and plenum. After installing the kit I am getting the same amount of shots , less FPS about 925 with everything maxed out on 135-140 bar .
what have I done wrong , it’s mk2 impact
