It sound like your gun is being starved of air pressure at high rates of speed. That narrows down the search too -
Tank being screwed to far in (like fallin said) and its shutting off the inflow of air.
Tank reg is set to output a low pressure (less than 400 psi) which gave me shoot down problems as well. I set mine to 650, anything above that will also work.
Tank reg may be incorrectly re-assembled. If you or anyone has serviced it recently, de-gass it and take another look at it.
Make sure that the orings are not only free of defects, but they are the correct size.
The LPR is set at 100psi straight from Critical. Once I tried to lower it and it wouldn't even cycle so I raised it back to 100. As for the tank its a HP Crossfire and it works great on every other gun so thats not it. I'll get some more air tomorrow and see if it makes a difference not screwing it in all the way..
Thaks for the help. I'm sure its something simple..
