Ok guys. My gun is the impact mk2 .25 cal. It have a slug power kit kit and 72 cc ppl installed. Front valve is past the 4th line so its fully open. I use the hex key to turn the screw next to the power wheel until the wheel can not turn anymore, so I know I'm max out. Then I back off a turn so the wheel will be able to turn again. Reg is set to 160 bar. I set power wheel to min and turn up after each shot. Shot over the chrony. Once the power wheel is on the 4, it will not increase speed anymore. Meaning, if I turn wheel to 5, will be same speed as 4. Then to max, still same speed as 4. What does this mean? Shouldnt the speed increase on 5 and max setting too? Is reg too high at 160 bar? I see folks setting their reg 170-190 bars, so 160 shouldn't be too high right?
