You'll probably hear from some more experienced Luxe techs soon enough on here, I myself am a much much better Ego and Intimidator tech, so I'm still learning the ins and outs of my luxe.
1. With your air on and dwell at 16, back your hpr screw out until the marker will not fire, and then slowly turn your hpr screw back in until the marker fires a good shot (280 fps+) again
2. adjust your dwell from 16 down till you see consistency, then adjust your hpr up or down to your desired velocity.
Again, I'm not a great Luxe tech yet lol but step 1 works wonders with most markers after a reg cleaning, and step 2 seems effective for me.
I buy Intimidator parts
