Just a quick update because no one has posted results after installing their bolts on this forum. Actually took the time to tune my shocker a bit at the field because out was a slow day. Set my dwell down to 8ms and I'm running around 175 psi. I'm still using an he can so that isn't the highest volume/lowest pressure setup. Initially the air vent from the qevs is startling when you aren't wearing a mask. Doesn't affect you when you have one on. But the softness of the shot is the biggest thing. The gun moves less than a luxe or the dm12 we shot side by side now. As this bolt breaks in I'm hoping to get hard efficiency numbers. All around, its an amazing upgrade.
