You mean micro at 4. That is maxed out. Macro wheel really says nothing.Little Update: I ended up achieving 1000 fps with the PW at 23 macro at 4 reg 150 bars using 34gr javelins. I removed the screw when I first got it. Just realized each one of us achieve that 1000 fps (34gr slugs) with different settings, thought I would copy and get the same results but it looks like each gun is different from the other.
You could consider a tungsten hamer. Your settings at micro will then be about 2. Just don't overdo the hamer if you want to keep that valve in good shape.
