shoot down prob. need help

[LadyBug]

I was shooting my A-4 and I noticed that when my fast rate of fire kicked in I was having drop offs. Here is the setting on my gun: 450 input pressure, not sure about mini reg, largest volumizer. And at the chrono I was shooting 290. If anyone could help, I would greatly appreciate it. :wall:

you need to check what your markers input pressure is

LPR is generally the culprit, however this is the first time I've heard of the 4 having any sort of shootdown. What's the Dwell at? Is the volumizer on the correct side? Are you sure this is shootdown and not something else? )ie reg beatdown on your air source)

What air source are you running?
