What happens is that the super heavy strike immediate opens the valve fully and then crashes back off the frame, allowing the valve to shut an instant later, releasing little air. Sooner, rather than later, that much hammer with so little reg pressure will damage the valve. As other said, Tungsten is only needed to open a valve that has a wall of 170+bar air keeping it closed. With a long barrel and such light slugs you should be running a pussy cat tune. With stock hammer (still way more than enough for your goal!), I’d go for 130 reg, open the valve knob fully and set the macro at its highest (then forget about it). Chrony shots starting from 2.0 on the micro. Click micro up 2 at a time till you reach your desired speed +10fps. Then incrementally close the valve knob (clockwise) until you lose that extra 10fps. That ensures that the valve is providing a short burst of air). Now, lots of folks are confused about this: The macro simply jogs the micro 5 clicks at a time. Play with it and watch the micro! Its utility is to find “presets” to use for different ammo at desired speeds. It allows the use of one tune to shoot different projectiles. You find their desired speed via trial and error and note the macro settings for each ammo (like macro 16 for your slugs and macro 5 for hades at 890fps). A bit like using channel presets on an old car radio. You can simply slip between slugs and hades by turning the macro, then go back to slugs, etc. The catch is that your primary tune (which is associated with the necessary reg pressure) should always be developed for your heaviest projectile. You can’t use this method to macro click to heavier/faster (more power; because that might require more reg pressure). That why I recommended tuning for the slug on the highest macro setting.
